Comparative study of miscellaneous properties of cysteine sulfinate transaminase and glutamate oxaloacetate transaminase in chick retina homogenate.
The activity, properties, and developmental pattern of cysteine sulfinate transaminase (CSA-T) were studied in chick retina and compared with the activity, properties, and developmental pattern of glutamate oxaloacetate transaminase (GOT). Their optimum pH is identical whereas the effect of pyridoxal phosphate seems to be different. Developmental patterns are also different. The Km and Vm of CSA-T and GOT were determined in chick retina homogenate. These results suggest that two different enzymes are responsible for the transamination of cysteine sulfinate (CSA) and aspartate.
