This domain is found in 7,8-dihydro-6-hydroxymethylpterin dimethyltransferase (HMPTM) and related proteins. HMPTM is involved in catalysing the methylation at C-7 and C-9 of 7,8-dihydro-6-hydroxymethylpterin, a common intermediate in both folate and MPT biosynthesis [1]. The domain represented by this entry is predicted to adopt a zinc beta-ribbon fold. It contains three invariant cysteines and one histidine arranged in two CxxC and CxxH sequence motifs.
Radical SAM proteins catalyse diverse reactions, including unusual methylations, isomerisation, sulphur insertion, ring formation, anaerobic oxidation and protein radical formation.
This family includes proteins containing domains which bind to iron-sulfur clusters. Members include bacterial ferredoxins, various dehydrogenases, and various reductases. The structure of the domain is an alpha-antiparallel beta sandwich.
