摘要：

Leukotriene A4 (LTA4) hydrolase belongs to the aminopeptidase N family. In order to investigate the molecular evolution and physiological significance of LTA4 hydrolase, the enzymes belonging to the family were aligned and a phylogenetic tree was constructed. From the alignment, it was found that three residues involved in zinc binding and one residue of the active sites of aminopeptidases N were conserved in LTA4 hydrolase. In agreement with the observation, LTA4hydrolase is a zinc protein as determined by atomic absorption spectroscopy. © 1990.
