From: The predominance of nucleotidyl activation in bacterial phosphonate biosynthesis

Bacterial cell surface modifications employing cytidylyl activation. a Proposed phosphonyl tailoring (Pnt) pathway logic based on its similarity to b the lipopolysaccharide core (Lic) pathway. c Putative gene clusters for three oral anaerobes under study, highlighting relevant genes for phosphocholine (P-Cho) and phosphonate tailoring. Black-colored genes are proposed to encode phosphonate-tailoring cytidyltransferases (PntCs) when located near ppm genes (red), and P-Cho cytidyltransferases (LicC) when located near other lic genes (e.g. those encoding LicA shown in yellow). For clarity, annotations for uncolored genes are not included
