4knf
From Proteopedia
Crystal structure of a blue-light absorbing proteorhodopsin double-mutant D97N/Q105L from HOT75
Function
[PRRB_PRB02] Light-driven proton pump. May have a regulatory rather than energy harvesting function, based on light-induced opening of proton channels, to modulate cell physiology depending on light intensity variations. Could be, therefore, a sensory rhodopsin, potentially associated with a transducer component.
About this Structure
4knf is a 5 chain structure with sequence from Gamma proteobacterium 'hot 75m4'. Full crystallographic information is available from OCA.
