Correct option is (d) D-xylose ketol-isomerase
The explanation is: International Union of Biochemistry appointed an “Enzyme commission” to provide proper systematic way of naming and classifying the enzymes. The commission assigned each enzyme a systematic name and a 4-digit code. D-xylose ketol-isomerase is a systematic name for glucose isomerase. Renin, Aspartate aminotransferase and glutathione synthetase are the common names of enzymes. L-aspartate: 2-oxoglutarate aminotransferase and g-L-glutamyl-L-cysteine: glycine ligase are systematic names for aspartate aminotransferase and glutathione synthetase respectively. Renin has not been given a systematic name till today.
