This family consists of uncharacterized proteins around 150 residues in length and is mainly found in various Arthrobacter species. The function of this family may be functional in enableing the growth of Arthrobacter sp. strain JBH1 with nitroglycerin as the sole source of carbon and nitrogen [1].
