Involved in 1,2-propanediol (1,2-PD) degradation by catalyzing the conversion of propanoyl-CoA to propanoyl-phosphate. phosphate + propanoyl-CoA = CoA + propanoyl phosphate There are 2 Zn(2+) ions per monomer; Zn(2+) and CoA bind inbetween the 2 domains in each monomer. Polyol metabolism; 1,2-propanediol degradation. Formed by 2 beta-barrels, each is capped on both ends by short alpha-helices. Belongs to the PduL family.
