N6-methyl-AMP deaminase activity

Definition

Target type: molecularfunction

Catalysis of the reaction: H+ + H2O + N6-methyl-AMP = IMP + methylamine. Can also use N6-methyl-dAMP as a substrate. [PMID:29884623, RHEA:16001]

N6-methyl-AMP deaminase activity is an enzymatic activity that catalyzes the deamination of N6-methyladenosine 5'-monophosphate (N6-methyl-AMP) to N6-methylinosine 5'-monophosphate (N6-methyl-IMP). This reaction involves the removal of an amino group from the N6 position of adenine in the N6-methyl-AMP molecule, resulting in the formation of a double bond between the N6 and C6 positions of the purine ring. The enzyme responsible for this activity is known as N6-methyl-AMP deaminase. This enzyme plays a crucial role in purine metabolism, particularly in the degradation pathway of N6-methyl-AMP, which is a minor nucleoside derivative found in tRNA and other cellular components. The N6-methyl-IMP produced by this reaction can be further metabolized into other purine derivatives or recycled back into the nucleotide pool. The N6-methyl-AMP deaminase activity is essential for maintaining proper purine homeostasis and ensuring the efficient utilization of purines in cellular processes. Its deficiency can lead to an accumulation of N6-methyl-AMP, potentially disrupting cellular metabolism and function.'
