Prolipoprotein diacylglyceryl transferase signature


Prolipoprotein diacylglyceryl transferase [1] is the bacterial enzyme that catalyzes the first step in lipoprotein biogenesis, it transfers the n-acyl diglyceride group on what will become the N-terminal cysteine of membrane lipoproteins. Prolipoprotein diacylglyceryl transferase (gene lgt) is an integral membrane protein.

As a signature pattern for this family, we selected a highly conserved region located in the central part of the protein.
