Meso_2403 | Methylthioadenosine phosphorylase; Purine nucleoside phosphorylase involved in purine salvage. (276 aa) | ||||
apt | Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis. (181 aa) | ||||
