31. The xylose isomerase from " Streptomyces olivochromogenes " is used in the food industry. 32. AGR2 is a protein disulfide isomerase , with CXXC active domain motifs for oxidation and reduction reactions. 33. This encoded protein is a cis-trans prolyl isomerase that binds the immunosuppressants FK506 and rapamycin. 34. The most common infections in people with triosephosphate isomerase deficiency are bacterial infections of the respiratory tract. 35. Phosphoglucose isomerase ( PGI ) is a housekeeping cytosolic enzyme with roles in both glycolysis and gluconeogenesis pathways. 36. One of them is FKBP-type peptidyl prolyl isomerase , which appears around 25kDa ( SlyD ). 37. Mannose-6-Phosphate Isomerase may also enable the synthesis of GDP-mannose in eukaryotic organisms. 38. This gene encodes a member of the peptidyl-prolyl cis-trans isomerase ( PPIase ) family. 39. The enzyme is a hexamer, forming the largest structurally known ketol isomerase , and has no residues. 40. The systematic name of this enzyme class is "'benzyl-thiocyanate isomerase " '.
