photosystem II 44 kDa subunit reaction center protein (also called P6 protein, CP43), bacterial and chloroplast; This model describes the Photosystem II, 44kDa subunit (also called P6 protein, CP43) in bacterial and its equivalents in chloroplast of algae and higher plants. Photosystem II is in many ways functionally equivalent to bacterial reaction center. At the core of Photosystem II are several light harvesting cofactors including plastoquinones, pheophytins, phyloquinones etc. These cofactors are intimately associated with the polypeptides, which principally including subunits 44 kDa protein,DI, DII, Cyt.b, Cyt.f, iron-sulphur protein and others. Functinally 44 kDa subunit is imlicated in chlorophyll binding. Together they participate in the electron transfer reactions that lead to the net production of the reducting equivalents in the form of NADPH, which are used for reduction of CO2 to carbohydrates(C6H1206). Phosystem II operates during oxygenic photosynthesis and principal electron donor is H2O. Although no high resolution X-ray structural data is presently available, recently a 3D structure of the supercomplex has been described by cryo-electron microscopy. Besides a huge body of literature exits that describes function using a variety of biochemical and biophysical techniques. [Energy metabolism, Electron transport, Energy metabolism, Photosynthesis]

chlorophyll a/b binding light-harvesting protein; This model represents a family of proteins from the Cyanobacteria, closely homologous to and yet distinct from PbsC, a chlorophyll a antenna protein of photosystem II. Members are not univerally present in Cyanobacteria, while the family has several members per genome in Prochlorococcus marinus, with seven members in a strain adapted to low light conditions. These antenna proteins may deliver light energy to photosystem I and/or photosystem II. [Energy metabolism, Photosynthesis]

of the residues that compose this conserved feature have been mapped to the query sequence.
Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
multi-domain models that were computationally detected and are likely to contain multiple single domains
