since the major activities of two other enzymes , serine : pyruvate aminotransferase ( ec 2.6.1.51 ) and glycerate kinase ( atp : d-glycerate 2-phosphotransferase , ec 2.7.1.31 ) , of the pathway via hydroxypyruvate are localized in mitochondrial inner membrane and/or matrix , the possible localization of d-glycerate dehydrogenase in mitochondria was examined .
