OsmC family protein
Osmotically inducible protein C (OsmC) (Swiss:P23929) is a stress -induced protein found in E. Coli. This family also contains a organic hydroperoxide detoxification protein (Swiss:O68390) that has a novel pattern of oxidative stress regulation [1]. [1]. 9573147. Identification and characterization of a new organic hydroperoxide resistance (ohr) gene with a novel pattern of oxidative stress regulation from Xanthomonas campestris pv. phaseoli. Mongkolsuk S, Praituan W, Loprasert S, Fuangthong M, Chamnongpol S;. J Bacteriol 1998;180:2636-2643. (from Pfam)
OsmC (osmotically inducible protein C) family protein may function as a peroxiredoxin or hydroperoxide reductase, catalyzing the reduction of organic and inorganic peroxide substrates to protect the cell against oxidative stress
OsmC family peroxiredoxin
Pfam model PF02566, OsmC-like protein, contains several deeply split clades of homologous proteins. The clade modeled here includes the protein OsmC, or osmotically induced protein C. The member from Thermus thermophilus was shown to have hydroperoxide peroxidase activity. In many species, this protein is induced by stress and helps resist oxidative stress.
