Protein Family Models

This family of dehydrogenases act on aldehyde substrates. Members use NADP as a cofactor. The family includes the following members: The prototypical members are the aldehyde dehydrogenases Swiss:P00352 EC:1.2.1.3. Succinate-semialdehyde dehydrogenase Swiss:P25526 EC:1.2.1.16. Lactaldehyde dehydrogenase Swiss:P25553 EC:1.2.1.22. Benzaldehyde dehydrogenase Swiss:P43503 EC:1.2.1.28. Methylmalonate-semialdehyde dehydrogenase Swiss:Q02252 EC:1.2.1.27. Glyceraldehyde-3-phosphate dehydrogenase Swiss:P81406 EC:1.2.1.9. Delta-1-pyrroline-5-carboxylate dehydrogenase Swiss:P30038 EC: 1.5.1.12. Acetaldehyde dehydrogenase Swiss:P17547 EC:1.2.1.10. Glutamate-5-semialdehyde dehydrogenase Swiss:P07004 EC:1.2.1.41. This family also includes omega crystallin Swiss:P30842 an eye lens protein from squid and octopus that has little aldehyde dehydrogenase activity. [1]. 9195888.

Succinic semialdehyde dehydrogenase is one of three enzymes constituting 4-aminobutyrate (GABA) degradation in both prokaryotes and eukaryotes, catalyzing the (NAD(P)+)-dependent catabolism reaction of succinic semialdehyde to succinate for metabolism by the citric acid cycle. The EC number depends on the cofactor: 1.2.1.24 for NAD only, 1.2.1.79 for NADP only, and 1.2.1.16 if both can be used. SSADH enzyme belongs to the aldehyde dehydrogenase family (PF00171), sharing a common evolutionary origin and enzymatic mechanism with lactaldehyde dehydrogenase [5]. Like in lactaldehyde dehydrogenase and succinate semialdehyde dehydrogenase, the mammalian catalytic glutamic acid and cysteine residues are conserved in all the enzymes of this family (PS00687, PS00070).
