  • PubMed Abstract: 

    Escherichia Coli GnsA is a regulator of phosphatidylethanolamine synthesis and functions as a suppressor of both a secG null mutation and fabA6 mutations. GnsA may also be a toxin with the cognate antitoxin YmcE. Here we report the crystal structure of GnsA to 1.8 Å. GnsA forms a V shaped hairpin structure that is tightly associated into a homodimer. Our comprehensive structural study suggests that GnsA is structurally similar to an outer membrane protein, suggesting a function of protein binding.
