    XVI.B.2.a. CP47

    CP47 is a chloroplast encoded polypeptide (psbB gene)(for a general review see Akerlund, 1993). It is exclusively Chl a binding (20-25 Chl a molecules). The polypeptide is closely associated with the reaction center. In addition to light harvesting it has been suggested that CP47 is also involved in anchoring other PSII apoproteins. CP47 appears to be an integral membrane protein with four membrane spanning helices (Rebeiz, unpublished).

    A query for CP47 addressed to the various protein databases listed in the Biology Workbench, yielded 14 records which are depicted under Sequenced CP47. These sequences can be used for Sequence Similarity Searches or other manipulations using one of several routines described in the Biology Workbench or elsewhere (see AntheproW which can be downloaded via anonymous ftp from: ibcp.fr; pub/Antheprot/Windows/anthe 3_1 directory). For example a Blast Sequence Similarity Search of tobacco CP47 addressed to the Biology Workbench (SwissProt database) is depicted below.
