Domain of unknown function (DUF4867) This family consists of uncharacterized proteins around 220 residues in length and is mainly found in various human gut Firmicutes and a few eubacteria species. It is also amply represented in human gut metagenomic datasets. Distant homology analysis and marginal HMM overlaps suggest this family is a distant homolog of Ureidoglycolate hydrolase pfam04115, but this prediction is not verified by experiment, therefore the function of this family is still unknown.
