The developmental patterns of enzyme activities related to GMP metabolism have been investigated in chick embryo musculus complexus (m. Complexus). Guanylate phosphatase activity increases conspicuously from 18th to 21st day, guanosine phosphorylase increases on the 21st day and the guanase shows a very low activity during the whole period considered. Xanthine oxidase was always found absent. The results suggest that during the first period of incubation GMP breakdown in chick embryo m. complexus might follow a catabolic pathway, while starting from the 18th day some guanine might be converted to GMP originating a new metabolic pathway as previously suggested for AMP metabolism.
