| Comments |
This enzyme catalyses the final step in the biosynthesis of L-ascorbic acid in higher plants and in nearly all higher animals with the exception of primates and some birds [5]. The enzyme is very specific for its substrate L-galactono-1,4-lactone as D-galactono-¦Ã-lactone, D-gulono-¦Ã-lactone, L-gulono-¦Ã-lactone, D-erythronic-¦Ã-lactone, D-xylonic-¦Ã-lactone, L-mannono-¦Ã-lactone, D-galactonate, D-glucuronate and D-gluconate are not substrates [5]. FAD, NAD+, NADP+ and O2 (cf. EC 1.3.3.12, L-galactonolactone oxidase) cannot act as electron acceptor [5]. |
