- Abstract
We have identified a cDNA encoding human peptidylglycine alpha-amidating monooxygenase (PAM; EC 1.14.17.3) with a total length of 3748 bp by screening of a human thyroid carcinoma lambda gt11 library using two heterologous oligonucleotides to conserved regions which derived from frog skin and bovine pituitary PAM sequences. Furthermore we have identified a sequence which differs in a 321 bp deletion. COS cells transfected with a truncated form of this cDNA (lacking the putative carboxyl-terminal transmembrane domain) generated a functional PAM that showed a 20-fold increase of the activity compared to the control and was visualized by immunoblotting.
