ID Q8MAG6_9CRYP Unreviewed; 465 AA. AC Q8MAG6; DT 01-OCT-2002, integrated into UniProtKB/TrEMBL. DT 01-OCT-2002, sequence version 1. DT 11-SEP-2007, entry version 20. DE Photosystem I P700 chlorophyll A apoprotein A1 (Fragment). GN Name=psaA; OS Pyrenomonas helgolandii. OG Plastid; Chloroplast. OC Eukaryota; Cryptophyta; Cryptomonadaceae; Pyrenomonas. OX NCBI_TaxID=141884; RN [1] RP NUCLEOTIDE SEQUENCE. RC STRAIN=SAG 28.87; RX MEDLINE=22199830; PubMed=12172008; DOI=10.1073/pnas.172234799; RA Yoon H.S., Hackett J.D., Bhattacharya D.; RT "A single origin of the peridinin- and fucoxanthin-containing plastids RT in dinoflagellates through tertiary endosymbiosis."; RL Proc. Natl. Acad. Sci. U.S.A. 99:11724-11729(2002). CC -!- FUNCTION: PsaA and psaB bind P700, the primary electron donor of CC photosystem I (PSI), as well as the electron acceptors A0, A1 and CC FX (By similarity). CC -!- SUBUNIT: The psaA/B heterodimer binds the P700 chlorophyll special CC pair and subsequent electron acceptors. PSI consists of a core CC antenna complex that captures photons, and an electron transfer CC chain that converts photonic excitation into a charge separation CC (By similarity). CC -!- SUBCELLULAR LOCATION: Membrane; multi-pass membrane protein (By CC similarity). CC -!- SIMILARITY: Belongs to the psaA/psaB family.
