evolution
the enzyme belongs to a dimethylsulfoxide reductase family of molybdenum enzymes, gene PSCT_04485 encoding IdrA (AioA) defines a distinct clade within the dimethylsulfoxide (DMSO) reductase family. The idr genes (idrABP1P2) form an operon-like structure
metabolism
Idr proteins and high affinity terminal oxidases (Cbb3 and Cyd), various H2O2 scavengers, and chlorite (ClO2 -) dismutase-like proteins are expressed specifically or abundantly under iodate-respiring conditions. Quantitative transcription analysis of the genes potentially involved in iodate respiration
physiological function
Pseudomonas sp. strain SCT is capable of using iodate (IO3-) as a terminal electron acceptor for anaerobic respiration. Periplasmic iodate reductase (Idr) is a possible key enzyme. Idr is a respiratory iodate reductase, and both O2 and H2O2 are formed as by-products of iodate respiration. Iodate-dependent H2O2 formation occurs biologically during iodate respiration
