ID 6.3.4.25 DE 2-amino-2'-deoxyadenylo-succinate synthase. CA ATP + dGMP + L-aspartate = (2S)-2-amino-2'-deoxyadenylo-succinate + ADP + CA 2 H(+) + phosphate. CC -!- The enzyme, characterized from a number of bacteriophages, CC participates in the biosynthesis of dZTP, which replaces dATP in the CC genome of these phages.
