1. The activities of protein disulphide-isomerase (PDI) and thioredoxin in catalysing disulphide bond isomerization in a protein substrate were compared by using the standard assay, namely the re-activation of 'scrambled' RNAase. 2. The specific activity of PDI was 25-fold greater than that of thioredoxin. 3. The greater efficiency of PDI compared with thioredoxin is considered to be due more to the presence of multiple catalytic domains in PDI than to differences in their active-site sequences. 4. Data and procedures were defined for expressing enzyme activity in standard units, i.e. mu-mol of active RNAase generated/min.
