Function
[HRSL3_HUMAN] Exhibits PLA1/2 activity, catalyzing the calcium-independent hydrolysis of acyl groups in various phosphatidylcholines (PC) and phosphatidylethanolamine (PE). For most substrates, PLA1 activity is much higher than PLA2 activity. Specifically catalyzes the release of fatty acids from phospholipids in adipose tissue (By similarity). N- and O-acylation activity is hardly detectable. Might decrease protein phosphatase 2A (PP2A) activity.[1] [2]
Publication Abstract from PubMed
H-REV107 is a Ca(2+)-independent phospholipase A(1/2), and it is also a pro-apoptosis protein belonging to the novel class II tumor suppressor family, H-REV107-like family. Here we report the solution structure of the N-terminal catalytic domain of human H-REV107, which has a similar architecture to classical NlpC/P60 domains, even though their fold topologies are different due to circular permutation in the primary sequence. The phospholipase active site possesses a structurally conserved Cys-His-His catalytic triad as found in NlpC/P60 peptidases, indicating H-REV107 should adopt a similar catalytic mechanism towards phospholipid substrates to that of NlpC/P60 peptidases towards peptides. As H-REV107 is highly similar to lecithin retinol acyltransferase, our study also provides structural insight to this essential enzyme in retinol metabolism.
