Abstract

Staphylococcus aureus capsule synthesis requires the precursor N-acetyl-glucosamine; however, capsule is synthesized during post-exponential growth when the availability of N-acetyl-glucosamine is limited. Capsule biosynthesis also requires aerobic respiration, leading us to hypothesize that capsule synthesis requires tricarboxylic acid cycle intermediates. Consistent with this hypothesis, S. aureus tricarboxylic acid cycle mutants fail to make capsule.
