XVI.B.1.c. Cytb559
All organisms that are capable of photosynthetic oxygen evolution contain cytochrome b559. (for a general review see Akerlund, 1993). The number of cytochrome b559 molecules per photosystem II appears to be one or two. Cytochrome b559 consists of two membrane-spanning subunits of 9 and 4 kDa which have a single histidine residue believed to be involved in heme binding.
A query for Cytb559 addressed to the various protein databases listed in the Biology Workbench, yielded 87 records which are depicted under Sequenced Cytb559. 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 the 9 kDa pea subunit of Cytb559 addressed to the Biology Workbench (SwissProt database) is depicted below. Another Blast Sequence Similarity Search of the 4 kDa pea subunit of Cytb559 addressed to the Biology Workbench (SwissProt database) is also depicted below
