Bacillus halodurans Bh2720 and related proteins, cupin domain
This family includes bacterial, archaeal, and eukaryotic proteins similar to Bh2720, a Bacillus halodurans protein of unknown function with a cupin beta-barrel fold.
Feature 1: metal binding site [ion binding site], 4 residue positions
Conserved feature residue pattern:[DE] [NH] Q H
Evidence:
Comment:The four-coordinate metallocenter usually includes three histidines and one glutamate; however, proteins in this subfamily may bind metal via different amino acids.
