| pubmed-article:2059626 | pubmed:abstractText | Carboxy-terminal amidation is a prevalent posttranslational modification necessary for the bioactivity of many neurohormonal peptides. We recently reported that in addition to peptidylglycine alpha-monooxygenase (PAM), a second enzyme, which we now call peptidylamidoglycolate lyase (PGL), functions in the enzymatic formation of amides [Katopodis et al. (1990) Biochemistry 29, 4551]. The monooxygenase first catalyzes formation of the alpha-hydroxyglycine derivative of the glycine-extended precursor, and the lyase subsequently catalyzes breakdown of the PAM product to the amidated peptide and glyoxylate. We report here the first primary sequence data for PGL, which establish that it is part of the putative protein precursor which also contains PAM. We also show that PAM and PGL activities are colocalized in the secretory granular fraction of neurointermediate pituitary as would be expected for enzymes sharing the same precursor. Time course studies of the amidation reaction using purified soluble pituitary PAM and PGL indicate that both enzymes are essential for enzymatic amidation. Finally, PGL has no effect on the substrate or inhibition kinetics of PAM, and purified pituitary PAM has an acidic pH optimum consistent with its known localization in secretory granules. | lld:pubmed |
