Microbiology

A triclosan-resistant bacterial enzyme

An Erratum to this article was published on 24 August 2000

Abstract

Triclosan is an antimicrobial agent that is widely used in a variety of consumer products and acts by inhibiting one of the highly conserved enzymes (enoyl-ACP reductase, or FabI) of bacterial fatty-acid biosynthesis. But several key pathogenic bacteria do not possess FabI, and here we describe a unique triclosan-resistant flavoprotein, FabK, that can also catalyse this reaction in Streptococcus pneumoniae. Our finding has implications for the development of FabI-specific inhibitors as antibacterial agents.
