The major light-harvesting antenna complex II (LHCII) in photsynthetic eukaryotes is located in the thylakoid membrane of the chloroplast. It is a heterotrimeric complex formed by up to 3 different individual subtypes of chlorophyll a/b-binding proteins: Lhcb1, Lhcb2, and Lhcb3. While Lhcb1 and Lhcb2 are quite similar and regularily present in multiple gene-copies, the Lhcb3 protein differs in pigment-composition and molecular size and often is coded by only a single gene. Lhcb3 seems not to be present in the mobile LHCII trimers involved in state 1-state 2 transitions. A molecular characterisation of the LHCII proteins can be found in Caffarri et al. (2004) A Look within LHCII: Differential Analysis of the Lhcb1−3 Complexes Building the Major Trimeric Antenna Complex of Higher-Plant Photosynthesis. Biochemistry 43 (29): 9467–9476.

KLH-conjugated synthetic peptide derived from known bacterial NifH subunits of bacterial nitrogenase enzymes of the FeMoCo type including Synechoccocus sp. Q2JP78 , Trichodesmium theibautii, Anabaena sp. P33178 and Nostoc sp. Q51296
Applications:
Immunofluorescence (IF), Immunohistochemistry (IHC), Western blot (WB)
An enzyme involved in chlorophyll synthesis, present in all cyanobacteria (fixing and non-nitrogen fixing) is a member of the NifH family/superfamily. Agrisera anti-NifH antibody will not show a strong reactivity to this target.In photobionts like Anabaena sp., low nitrate growth is required to turn on the NifH expression to high enough levels to detect NifH protein. Immunofluorescence protocol Insect dissected tissues (digestive tract, fat body, carrying NifH positive bacteria) of large workers were fixed in cold methanol (20 min, -20 °C) and then permeabilized in cold acetone (5 min, -20 °C). Samples were subsequently rinsed three times with PBS with 0.1 % Triton-X 100 at RT (PBST) and incubated for 5 minutes in PBST. This was followed by incubation of tissues for 1 hr with 6 ug/ml affinity purified anti-NifH antibody (Agrisera, AS01 021A) diluted in PBS-TBSA (PBS, 0.1 % v/v Triton-X-100, 1 mg/ml BSA) and 3 washings with PBST. Samples were then incubated in the dark with a goat anti-chicken IgY conjugated to Dylight 488 (Pierce, SA5-10070) for 45 min and were washed twice (PBS, 0.1%v/v Triton-X-100). Finally, the tissues were mounted in Vectashield medium containing DAPI (Vector Laboratories, H-1500) and viewed under a SP5 Leica confocal microscope with 10X and 63X objectives. Courtesy of Drs.

Lhcb4 (CP29) is one of the 3 minor chlrorophyll a/b-binding proteins associated with Photosystem II in plants and algae. Lhcb4 has been suggested to act in the regulation of the chl a excited state concentration of PSII because of its ability of sensing lumenal pH resulting in reversible phosphorylation. In Arabidopsis thaliana 2 genes code for two isoforms Lhcb4.1 and Lhcb4.2. A third isoform (Lhcb4.3, At2g40100), probably only present in dicots, has found to be differently regulated and therefore has been denoted as Lhcb8.

Chlorophylls are one of the most abundant classes of natural pigments and have an essential role in radiant energy absorptions during photosynthesis in bacteria, algae, and higher plants. Chlorophylls occur as noncovalently bound components of pigment-protein complexes, chloroplast-localized light-harvesting antennas LHC and photosynthetic reaction centers of PSI and PSII. Upon illumination the arrest in chlorophyll biosynthesis is ended and the etiolated parts of the plant and enzymatic photoreduction of protochlorophyllide (Pchlide) to chlorophyllide (Chlide), catalysed by POR enzyme.

Lhca5 is a low abundant chlorophyll a/b-binding protein that has been found to associate with Photoystem I in sub-stoechiometric amounts. Unlike the four main Lhca-types (Lhca1-4) Lhca5 seems to be able to associate with PSI or the LHCI at varying positions. The regulation pattern for the expressino of the Lhca5 gene differs from the standard Lhc pattern as expression seems to be positively regulated under light and cold stress conditions.

PsaL (PSI-L) is a conserved subunit of type I photosynthetic reaction centers (Photosystem I, PSI). PSI is an integral membrane multi-protein complex that catalyzes the electron transfer from plastocyanin (or cytochrome c6) to ferredoxin (or flavodoxin). Psa-L is binding pigments and has been shown to be involved in trimerization of PSI in cyanobacteria (but not in plants) and bind pigments in plants and cyanobacteria.In plants and algae Psa-L is nuclear encoded and imported post-translationally into the chloroplast where it inserts into the thylakoid membrane.

Lhcb4 (CP29) is a member of the family of chlorophyll a/b-binding proteins, which is conserved in higher plants and green algae. Lhcb4 is associated with Photosystem II serving both as a light-harvesting antenna protein as well as playing a role in photoprotective dissipation of excitation energy. The Chlamydomonas homolog of plant Lhcb4 has also been denoted as Lhcbm4.

Multi-subunit complex of cytb6/f is a crucial component for the photosynthetic electron transport chain of higher plants, green algae and cyanobacteria. This complex is catalyzing oxidation of quinols and the reduction the reduction of plastocyanin. This reaction allows to establish the proton force required for the ATP synthesis. Four major subunits build the complex: the petA gene product corresponding to a c-type cytochrome (cytf), the petB gene product corresponding to a b-type/c’-type cytochrome with three haems (cyt b6), the petD gene product (subunit IV, or suIV), and the petC gene product, corresponding to the Rieske/Iron/sulfur protein.

PSII reaction centre components are generating the redox potential required to drive highly oxidizing water splitting reaction. Four Mn atoms are present on a lumenal surface and form the catalyctic site of the water-splitting reaction which is in close association with the 33 kDa (PsbO), 23 kDa (PsbP) and 17 kDa (PsbQ) extrinistic subunits of oxygen evolving complex OEC. A 33-kDa extrinsic protein is also termed the Mn-stabilizing protein (MSP), however recent evidences shown that it is C-terminal domain of PsbA (D1) protein which is involved in in the assembly and stabilization of the OEC.

The PsbH protein was originally named 10- or 9-kDa phosphoprotein in higher plant chloroplasts. It is encoded by the plastome in algae and higher plants. PsbH is also present in cyanobacteria, where it exhibits 56% amino acid identity with the corresponding protein from Arabidopsis. The protein contains 63–90 amino acids, depending on the species, with molecular masses between 7.0 and 9.9 kDa.PsbH is an intrinsic membrane protein with a single transmembrane helix and its N-terminal region has been suggested to be exposed to the stromal side of the thylakoid membrane. Presence of PsbH already present in etiolated tissue can indicate that the protein may be involved in early stages of PSII assembly.Obtained biochemical data from PSII complexes isolated from spinach suggest that PsbH, together with other PSII phosphoproteins, may be required for D1 protein turnover by regulating dimeric and monomeric PSII transition through their phosphorylation and dephosphorylation.
