Schematic representation of conserved domains within ncpA and ncpB coding nucleotide sequences. They are composed of repetitive modules condensation (C), adenylation (A) and peptidyl carrier protein (PCP) domains adjacent to delineating docking, epimerization and reductase domains aligned with two related synthetases AY167420.1 and CP026681.1. The analysis was conducted at the nucleotide level.
