Chains Pfam Accession Pfam Identifier Pfam Description Type Source
A PF14890 Intein_splicing Intein splicing domain Family
A PF14528 LAGLIDADG_3 LAGLIDADG-like domain Domain This domain is part of the LAGLIDADG superfamily [1]. PFAM PF14528
A PF14890 Intein_splicing Intein splicing domain Family
A PF09062 Endonuc_subdom PI-PfuI Endonuclease subdomain Domain The endonuclease subdomain, found in the prokaryotic protein ribonucleotide reductase, assumes an alpha-beta-beta-alpha-beta-beta-alpha-alpha topology. The four stranded beta-sheet forms a saddle-shaped surface and assembles together through an interface made of alpha-helices. The presence of 14 basic residues on the surface of the beta-sheets suggests that this large groove may be involved in DNA binding [1]. PFAM PF09062
A PF09061 Stirrup Stirrup Domain The Stirrup domain, found in the prokaryotic protein ribonucleotide reductase, has a molecular mass of 9 kDa and is folded into an alpha/beta structure. It allows for binding of the reductase to DNA via electrostatic interactions, since it has a predominance of positive charges distributed on its surface [1]. PFAM PF09061
