    The human general transcription factor TFIIH is involved in both transcription and DNA nucleotide excision repair. Among the 10 subunits of the complex, p44 subunit plays a crucial role in both mechanisms. Its N-terminal domain interacts with the XPD helicase, whereas its C-terminal domain is involved specifically in the promoter escape activity. By mutating an exposed and non-conserved cysteine residue into a serine, we produced a soluble mutant of p44-(321-395) suitable for solution structure determination. The domain adopts a C4C4 RING domain structure with sequential organization of beta-strands that is related to canonical RING domains by a circular permutation of the beta-sheet elements. Analysis of the molecular surface and mutagenesis experiments suggests that the binding of p44-(321-395) to TFIIH p34 subunit is not mediated by electrostatic interactions and, thus, differs from previously reported interaction mechanisms involving RING domains.
