Bradyrhizobium japonicum BLR7677 and related proteins, cupin domain
This family includes bacterial and fungal proteins homologous to BLR7677, a Bradyrhizobium japonicum protein of unknown function. Proteins in this family belong to the cupin superfamily with a conserved "jelly roll-like" beta-barrel fold capable of homodimerization.
Feature 1: putative metal binding site [ion binding site], 3 residue positions
Conserved feature residue pattern:H H H
Evidence:
Comment:The metal binding site is usually a four-coordinate metallocenter that includes three histidines and one glutamate; however, proteins in this subfamily only contain three conserved metal-binding residues
