UbenimexLeucyl aminopeptidase: Leucyl aminopeptidases (, leucine aminopeptidase, LAPs, leucyl peptidase, peptidase S, cytosol aminopeptidase, cathepsin III, L-leucine aminopeptidase, leucinaminopeptidase, leucinamide aminopeptidase, FTBL proteins, proteinates FTBL, aminopeptidase II, aminopeptidase III, aminopeptidase I) are enzymes that preferentially catalyze the hydrolysis of leucine residues at the N-terminus of peptides and proteins. Other N-terminal residues can also be cleaved, however.Glutamyl aminopeptidase: Glutamyl aminopeptidase (, aminopeptidase A, aspartate aminopeptidase, angiotensinase A, glutamyl peptidase, Ca2+-activated glutamate aminopeptidase, membrane aminopeptidase II, antigen BP-1/6C3 of mouse B lymphocytes, L-aspartate aminopeptidase, angiotensinase A2) is an enzyme encoded by the gene. Glutamyl aminopeptidase has also recently been designated CD249 (cluster of differentiation 249).Alanine aminopeptidase: Alanine aminopeptidase () is an enzyme that is used as a biomarker to detect damage to the kidneys, and that may be used to help diagnose certain kidney disorders. It is found at high levels in the urine when there are kidney problems.Protein N-terminal methyltransferase: Protein N-terminal methyltransferase (, NMT1 (gene), METTL11A (gene)) is an enzyme with system name S-adenosyl-L-methionine:N-terminal-(A,P,S)PK-(protein) methyltransferase. This enzyme catalyses the following chemical reactionPyrrolidonyl peptidase: Pyrrolidonyl peptidase is an enzyme found in certain bacteria.Specificity constant: In the field of biochemistry, the specificity constant (also called kinetic efficiency or k_{cat}/K_{M}), is a measure of how efficiently an enzyme converts substrates into products. A comparison of specificity constants can also be used as a measure of the preference of an enzyme for different substrates (i.MicrovillusProtein primary structure: The primary structure of a peptide or protein is the linear sequence of its amino acid structural units, and partly comprises its overall biomolecular structure. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end.Dipeptidyl-peptidase IV family: In molecular biology, the dipeptidyl-peptidase IV family is a family of serine peptidases which belong to MEROPS peptidase family S9 (clan SC), subfamily S9B (dipeptidyl-peptidase IV). The protein fold of the peptidase domain for members of this family resembles that of serine carboxypeptidase D, the type example of clan SC.Coles Phillips
