Leucine aminopeptidase

UniProtKB accession:  Q8IL11

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Aminopeptidase which preferentially cleaves leucine residues from the N-terminus of peptides (PubMed:17107951, PubMed:21844374, PubMed:22359643, PubMed:33536500, PubMed:34133730). Also, has some activity towards tryptophan and methionine and to a lesser extent towards phenylalanine (PubMed:17107951, PubMed:22359643, PubMed:34133730). Has very low activity or no activity towards the other amino acids (PubMed:17107951, PubMed:22359643, PubMed:34133730). In addition, cleaves the Cys-Gly dipeptide, probably as part of the glutathione regulation pathway; cleavage only occurs in the presence of Mn(2+) (PubMed:33303633). During the asexual blood stage, plays a role in the final step of host hemoglobin catabolism, by cleaving hemoglobin-derived oligopeptides providing a source of amino acids for the parasite protein synthesis and for the maintenance of osmotic homeostasis (PubMed:34133730). During the asexual blood stage, may also play a role during the ring-trophozoite transition (PubMed:21844374).
