Structural highlights

Disease

PTSS1_HUMAN Lenz-Majewski hyperostotic dwarfism. The disease is caused by variants affecting the gene represented in this entry.

Function

PTSS1_HUMAN Catalyzes a base-exchange reaction in which the polar head group of phosphatidylethanolamine (PE) or phosphatidylcholine (PC) is replaced by L-serine (PubMed:19014349, PubMed:24241535). Catalyzes mainly the conversion of phosphatidylcholine (PubMed:19014349, PubMed:24241535). Also converts, in vitro and to a lesser extent, phosphatidylethanolamine (PubMed:19014349, PubMed:24241535).^{[1] [2]}
