Transamination of glutamic acid during germination, growth and seed development in Bengal gram

Abstract

The activity of glutamic acid aminotransferase with respect to six keto acids was studied in dialysed extracts obtained from germinating seeds, leaves of plants at seedling, preanthesis and postanthesis stages and the developing seeds of Bengal gram. There was a considerable amount of non-enzymic aminotransferase activity which changed at different stages of growth. The efficiency of glutamic acid to transfer amino group to various keto acids also varied in two different varieties in relation to growth and development. The possibility of the existence of either many aminotransferases or of several isozymes is discussed.
