The enzymes are usually named according to the substrate, such as adenosine deaminase, guanine deaminase, or guanosine deaminase. Also called aminohydrolase. deaminase an enzyme causing deamination, or removal of an amino group from organic compounds, named according to its substrate as adenosine deaminase, cytidine deaminase, guanine deaminase, etc. How to thank TFD for its existence?

These include aminolevulinate (ALA) dehydratase, porphobilinogen deaminase (hydroxymethylbilane synthase), and uroporphyrinogen decarboxylase in spleen and ALA synthase in liver. In addition, new programs in protein engineering (37) of subtilisin BPN' (3,38-50) and hemoglobin (7,51-56) were carried out as well as detailed structural investigations of a number of enzymes that included ribonuclease (57-64), several glutathione S-transferases (6,65-82), uracil DNA glycosylase (8,83-84), threonine deaminase (85-86), and nucleoside diphosphosphate transferase (87-88). In triple sugar iron agar, it was negative for citrate, phenylalanine deaminase, and indol production. |
