- The thioredoxin system including thioredoxin and thioredoxin reductase (TrxR) is used for oxidative stress defenses in fungi. Based on the genomic sequence, a thioredoxin reductase-encoding gene (ActrxR1) was isolated from Acremonium chrysogenum CGMCC3.3795. Like other TrxRs, AcTrxR1 contains FAD bi

- YknXYZ is the ATP-binding cassette export complex from Bacillus subtilis, where YknX is a membrane fusion protein, YknY is an ATPase, and YknZ is a permease. The yknXYZ genes are arranged into an operon that also includes yknW, encoding a membrane protein with four putative transmembrane segments. P
