Different CAS Registry Numbers [1] are used for each form of a substance. For example, something simple like alanine will have one CAS# for the D form, another for L, another for "unspecified" and a fourth one for racemic. There would be another four CAS#s for the hydrochloride, four for the (1:1) sulfate, four for the (2:1)sulfate, etc.
D-sedoheptulose 7-phosphate + phosphate acetyl phosphate + D-ribose 5-phosphate + H 2 O [3] Phosphoketolase is considered a promiscuous enzyme because it was demonstrated to use 3 different sugar phosphates as substrates.
In enzymology, a 2,5-dihydroxypyridine 5,6-dioxygenase (EC 1.13.11.9) is an enzyme that catalyzes the chemical reaction. 2,5-dihydroxypyridine + O 2 N-formylmaleamic acid. The 2 substrates of this enzyme are 2,5-dihydroxypyridine and O 2, whereas its product is N-formylmaleamic acid. [1]
