Adds a myristoyl group to the N-terminal glycine residue of certain cellular proteins (By similarity). Myristoylates adenylate kinase AK2 (By similarity). During the asexual blood stage, may myristoylate proteins such as ARO, CDPK1 and GAP45 (PubMed:34695132). Probably by mediating protein myristoylation, plays a role in the assembly of the inner membrane complex during the early stages of schizogony and in the formation of rhoptries in the late stages and thus merozoite egress (PubMed:34695132). N-terminal glycyl-[protein] + tetradecanoyl-CoA = CoA + H(+) + N-tetradecanoylglycyl-[protein] Heterodimer composed of NMT and AK2; AK2 myristoylation stabilizes the complex. Belongs to the NMT family.
