Function

MCPB_PSEAE Chemoreceptor that plays a critical role in the virulence and pathogenesis of P.aeruginosa in a variety of hosts (PubMed:31511598). Probably acts through oxygen sensing (PubMed:31511598, PubMed:28167524, PubMed:34383467). Uses a heme-based sensor (PubMed:21255112, PubMed:22622145). Could be involved in chemotaxis (PubMed:12142407, PubMed:14987771). When expressed in E.coli, is able to sense and mediate repellent responses to oxygen, carbon monoxide and nitric oxide (PubMed:21255112).[1] [2] [3] [4] [5] [6] [7]
