Metabolism of glycerate-2,3-P2--VII. Enzymes involved in the metabolism of glycerate-2,3-P2 in cat tissues.

The levels of the enzymes involved in the metabolism of glycerate-2,3-P2 (phosphoglycerate mutase, bisphosphoglycerate synthase-phosphatase and bisphosphoglycerate phosphatase) in cat and in pig tissues are different. The main difference is the low level of bisphosphoglycerate synthase-phosphatase in cat tissues. As a consequence, in contrast with pig erythrocytes, in cat erythrocytes, both the synthesis and the breakdown of glycerate-2,3-P2 are mainly controlled by phosphoglycerate mutase.
