    Protein Summary

    The mll5367 gene from Mesorhizobium loti encodes a choline/ethanolamine kinase (PF01633, COG0510, EC: 2.7.1.32). The structure comprises two alpha+beta domains with a protein kinase-like fold that shows significant structural similarity to human cholin kinases (PDB id: 2IG7, 2I7Q). In bacteria, choline kinase is predicted to be involved in lipopolysaccharide (LPS) biosynthesis. The presence of phosphorylcholine on LPS has been shown to differentiate commensal from pathogenic bacteria [Ref], suggesting that this enzyme may play a broader role in immune avoidance.
