poly(ADP-ribose) glycohydrolase domain-containing protein
Poly(ADP-ribose) glycohydrolase (PARG) hydrolyses the ribose-ribose bonds present in poly(ADP-ribose) (PAR) chains. This entry represents the PARG homologue present in bacteria and fungi. Its structure shows a typical macrodomain folding consisting of a seven-stranded beta-sheet sandwiched between nine alpha-helices [1,2]. [1]. 21892188.

TIGR02452 family protein
Members of this uncharacterized protein family are found in Streptomyces, Nostoc sp. PCC 7120, Clostridium acetobutylicum, Lactobacillus johnsonii NCC 533, Deinococcus radiodurans, and Pirellula sp. for a broad but sparse phylogenetic distibution that at least suggests lateral gene transfer.
