InterPro : IPR004508

Name  Thioredoxin-independent 5'-adenylylsulphate reductase Short Name  Thioredoxin-indep_APS_Rdtase
Type  Family Description  This enzyme, involved in the assimilation of inorganic sulphate, is closely related to the thioredoxin-dependent PAPS reductase of Bacteria (CysH) and Saccharomyces cerevisiae. However, it has its own C-terminal thioredoxin-like domain and is not thioredoxin-dependent. Also, it has a substrate preference for 5'-adenylylsulphate (APS) over 3'-phosphoadenylylsulphate (PAPS) so the pathway does not require an APS kinase (CysC) to convert APS to PAPS. Arabidopsis thalianaappears to have three isozymes, all able to complement Escherichia coliCysH mutants (even in backgrounds lacking thioredoxin or APS kinase) but likely localized to different compartments in Arabidopsis.
