Figure 6From: Characterization of hemin-binding protein 35 (HBP35) in Porphyromonas gingivalis: its cellular distribution, thioredoxin activity and role in heme utilizationThioredoxin-catalyzed reduction of insulin by DTT. Increase in turbidity at 650 nm was plotted against reaction time. Closed diamond, rHBP35(Q22-P344) plus DTT; closed square, E. coli thioredoxin plus DTT; closed triangle, rHBP35(Q22-P344 with C48S C51S) plus DTT; X, rHBP35(Q22-P344) without DTT.Back to article page
