== Function ==
[https://www.uniprot.org/uniprot/MCPB_PSEAE 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:28167524, PubMed:31511598, 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).<ref>PMID:12142407</ref> <ref>PMID:14987771</ref> <ref>PMID:21255112</ref> <ref>PMID:22622145</ref> <ref>PMID:28167524</ref> <ref>PMID:31511598</ref> <ref>PMID:34383467</ref>

== Publication Abstract from PubMed ==
The crystal structure of a truncated Aer2, a signal transducer protein from Pseudomonas aeruginosa, consisting of the heme-containing PAS and di-HAMP domains revealed that a distal tryptophan residue (Trp283) plays an important role in stabilizing the heme-bound O(2) and intra-molecular signal transduction upon O(2) binding.

Structural basis for oxygen sensing and signal transduction of the heme-based sensor protein Aer2 from Pseudomonas aeruginosa.,Sawai H, Sugimoto H, Shiro Y, Ishikawa H, Mizutani Y, Aono S Chem Commun (Camb). 2012 Jul 4;48(52):6523-5. doi: 10.1039/c2cc32549g. Epub 2012 , May 23. PMID:22622145<ref>PMID:22622145</ref>
