Family Report for: Mg-chelatase_BchO


Block X
Parent Family : Abhydrolase_6

(from InterPro) Putative magnesium chelatase accessory protein (IPR017497) : Members of this entry belong to the alpha/beta fold family of hydrolases. Members are found in bacterial genomes, if and only if, they encode anoxygenic photosynthetic systems similar to that found in Rhodobacter capsulatus (Rhodopseudomonas capsulata) and other alpha-Proteobacteria. Also proteins in this entry are often encoded in the same operon as subunits of the protoporphyrin IX magnesium chelatase, and were once designated BchO. No literature supports a role as an actual subunit of magnesium chelatase, but an accessory role is possible, as suggested by its genomic context and by its probable hydrolase activity. Hajighasemi et al. presented biochemical and structural insights into enzymatic depolymerization of polylactic acid and other polyesters.
