Protein Domain : DUF34/NIF3 superfamily IPR036069

Type	Homologous_superfamily
Description	This superfamily includes DUF34/metal-binding proteins (also known as GTP cyclohydrolase 1 type 2 proteins) from bacteria, NIF3 from budding yeasts and NIF3-like proteins from animals.This entry includes the DUF34/metal-binding protein/NIF3 proteins, which are widely distributed across superkingdoms. They were previously annotated as GTP cyclohydrolase 1 type 2 [ ] and, recently, through a comprehensive literature review and integrative bioinformatic analyses it was revealed that annotations for these members are misleading as they were based on a single set of in vitro results examining the NIF3 homolog of Helicobacter pylori []. Actually, they have varied phenotypes with the unifying functional role as metal-binding proteins [].NIF3 interacts with the yeast transcriptional coactivator Ngg1p which is part of the ADA complex, the exact function of this interaction is unknown [ , ].
