abstract

  • ABSTRACT There have been considerable strides made in the characterization of the dispensability of teichoic acid biosynthesis genes in recent years. A notable omission thus far has been an early gene in teichoic acid synthesis encoding the N -acetylmannosamine transferase ( tagA in Bacillus subtilis ; tarA in Staphylococcus aureus ), which adds N -acetylmannosamine to complete the synthesis of undecaprenol pyrophosphate-linked disaccharide. Here, we show that the N -acetylmannosamine transferases are dispensable for growth in vitro, making this biosynthetic enzyme the last dispensable gene in the pathway, suggesting that tagA (or tarA ) encodes the first committed step in wall teichoic acid synthesis.
