Abstract: | Most Actinobacteria produce mycothiol as the major thiol. In addition to mycothiol Rhodococcus AD45 generates a substantial level of glutathione possibly using genes acquired in a lateral transfer. Instead of mycothiol, Rubrobacter radiotolerans and Rubrobacter xylanophilus produce glutathione, whose synthesis appears to involve enzymes substantially different from those in other organisms. |
