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.

PsaD (PSI-D) is a core subunit of photosystem I highly conserved in all photosynthetic organisms (including bacteria with Fe-S type reaction centers). In eukaryots its encoded by 1 to 2 nuclear gene(s) and imported as a precursor into the chloroplast. In the thylakoid membrane it associates with PsaA and PsaB on the stromal site of the PSI core forming the Fd-docking site. PsaD is also required for the stable assembly of PsaC.

PEB is an extraction buffer for disruption and solubilisation of total protein from plant tissue and algal cells. The use of the anionic detergent LDS together with the recommended procedure (combination of sonication and freeze/thaw cycles) has been shown to increase the number of solubilised and non-degraded proteins when compared to other methods of cell disruption (see reference). The estimated hands-on time for the recommended procedure is 20-30 minutes for 1-2 samples. Expected yields will be 1.5-6 g/ l total protein (recovered from standard procedure) depending on the starting material, e.g. its biological stage, homogenization method used (bead beater vs. sonication).
Product Type:
Antibody
Storage Temp:
Stable at RT for at least 1 month; short-term storage (6 monthss) at 4°Cand long term storage (1 year or more) at -20 °C.
Species Reactivity:
PEB has been tested on a wide range of species and tissues from Higher plants, Mosses, Llichens, Algae, Diatoms, Dinoflagellates, Cyanobacteria. Extracts may be quantified using detergent (LDS) compatible methods, and have been shown to give highly reproducible and quantitative results in subsequent SDS PAGE gel electrophoresis, Western blotting, and Immunoprecipitation (IP). Most of Agrisera commercial antibodies are tested on plant or algal samples extracted with this buffer. An example can be found here.
5 x 2 ml (4x stock) allows up to 75 isolations of plant material (using 500 µl 1x PEB for 100 mg fresh weight) or 190 isolations of algal material (using 200 µl 1x PEB for cell amounts corresponding to 4-10 µg total chlorophyll)

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.

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.

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.

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.

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.

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.

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.
