ArsO family NAD(P)H-dependent flavin-containing monooxygenase
All members of the seed alignment for this HMM, including founding member ArsO (ABB70173.1), are encoded in arsenic resistance islands. However, protein functions in this family maybe both variable and promiscuous. ArsO is related to the flavoprotein CzcO (see PMID:12100555), which was found to modestly enhance the activity of cation diffusion facilitator CzcD.
