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.

This enzyme is proposed to act in the ring-opening step of phenylacetic acid degradation [1] which follows ligation of the acid with coenzyme A (by PaaF) and hydroxylation by a multicomponent non-heme iron hydroxylase complex (PaaGHIJK). Gene symbols have been standardized in [2]. This enzyme is related to aldehyde dehydrogenases and has a domain which is a member of the PF00171 family. This family includes sequences from Burkholderia, Bordetella, Streptomyces. Other PaaN enzymes are represented by a separate model, TIGR02278.
