AroY: Catalyzes protocatechuate to catechol

AroY codes for the protocatechuate deacarboxylase from Klebsiella pneumonie ssp. pneumonie. It has a molecular mass of 57 kDa and is reported to form a complex of five identical AroY subunits. [http://2012.igem.org/Team:TU_Darmstadt/Modeling_GNM#AroY Gaussian network modelling] showed a flexible helix linker. This could be either a membrane anchor or responsible for the formation of a pentamer.

Usage and Biology

AroY is reported to catalyze the reaction of protocatechuate (3,4-Dihydroxybenzoate) to catechol under anaerobic conditions.
