Recombinant Human Peptidylglycine Alpha-Amidating Monooxygenase, His-tagged

Cat. No.: PAM-495H
Product Overview: Recombinant Human PAMis expressed in Murine myeloma cell line, which has a molecule weight of 90 kDa. Met1­ Val817, with a C­terminal 10­His tag.
Description: Pedptidylglycine α­AmidatingMonooxygenase (PAM) catalyzes the C­terminal amidation that is required for thefunction of a number of peptide hormones. PAM possesses two enzymatic activitieson a single polypeptide chain, due to the presense of a peptidylglycine α­hydroxylatingmonooxygenase (PHM) domain and a peptidyl­α­hydroxyglycine α­amidating lyase (PAL)domain. The C­terminal glycines of precursor peptides are hydroxylated at theglycine α carbon by the PHM activity in a reaction that requires ascorbate, thenthe PAL activity completes the amidation, releasing glyoxylate in the process.PAM is required for the biosynthesis of peptides such as Substance P, neuropeptideY, oxytocin, vasopressin, and calcitonin. PAM is highly expressed in tissues thatsynthesize bioactive peptides, such as the thyroid and pituitary glands. The enzymeis generally stored in secretory granules, but soluble secreted forms have beenobserved. Recombinant human PAM was expressed as a C­terminally truncated proteinlacking its transmembrane and cytosolic domains to facilitate its secretion.
