Báo cáo khoa học: Identification of malic and soluble oxaloacetate decarboxylase enzymes in Enterococcus faecalis

Two paralogous genes,maeEandcitM, that encode putative malic enzyme family members were identified in the Enterococcus faecalisgenome. MaeE (41 kDa) and CitM (42 kDa) share a high degree of homology between them (47% identities and 68% conservative substitutions). However, the genetic context of each gene suggested thatmaeEis associated with malate utilization whereascitM is linked to the citrate fermentation pathway.
