Crystal structure of the orange carotenoid protein Y44S mutant from cyanobacteria synechocystis sp. PCC 6803
Template:ABSTRACT PUBMED 20368334
Function
[OCP_SYNY3] Acts as a photo-protectant. Essential for inhibiting white and blue-green light non-photochemical quenching (NPQ). Binding carotenoids improves OCP's intrinsic photoprotectant activity by broadening its absorption spectrum and facilitating the dissipation of absorbed energy.[1]
About this Structure
3mg2 is a 2 chain structure with sequence from Synechocystis sp.. This structure supersedes the now removed PDB entry 3i1w. Full crystallographic information is available from OCA.
