Adenine phosphoribosyltransferase in plant tissues: some effects of kinetin on enzymic activity.

P B Nicholls1, A W Murray.   

Abstract

Adenine phosphoribosyltransferase activity was measured in extracts of soybean (Glycine max var. Acme) callus and of senescing barley leaves (Hordeum distichon c.v. Prior). The enzyme from soybean callus had Michaelis constants for adenine and 5-phosphoribosyl pyrophosphate of 1.5 and 7.5 mum respectively and was inhibited by AMP and stimulated by ATP. The presence of kinetin was found to considerably increase the activity of adenine phosphoribosyltransferase in extracts of soybean callus and senescing barley leaves.
