Functional Analysis of cha Genes Identifies ChaC as a Glutathione-Degrading Enzyme Rather Than a Sodium Transport Regulator

Hibiki Sawada, Naoko Ohkama‐Ohtsu, Takehiro Ito

This study clarifies that ChaC in E. coli functions in glutathione degradation rather than sodium transport, and ChaB is not involved in GSH metabolism.
