== Function ==
[https://www.uniprot.org/uniprot/CY550_SYNY3 CY550_SYNY3] Low-potential cytochrome c that plays a role in the oxygen-evolving complex of photosystem II (PSII). Required for normal function or stabilization of PSII. Extrinsic protein associated with PSII that enhances oxygen evolution.

== Publication Abstract from PubMed ==
The crystal structure of low-potential cytochrome c549, an extrinsic component of the photosystem II (PS II) from Synechocystis sp. PCC 6803, was obtained directly from single-wavelength 1.21 A resolution diffraction data. This is the first monodomain bis-histidinyl monoheme cytochrome c to be structurally characterized. The extended N-terminal region of c549 builds up a two-strand antiparallel beta-sheet in a hairpin motif, which extends through two molecules owing to crystal packing. Both peptide termini are involved in crystal contacts, which may explain their protrusion out of the globular fold. The C-terminus is preceded by a 9 A-long hydrophobic finger extending from a positively charged base and could be involved in PSII interactions, as well as a protruding negative patch built by a set of conserved acidic residues among c549 sequences.
