Cor consists entirely of this domain with homologues in a variety of organisms, including most mycobacteria, Bacteroides sp., Chlamydia sp., Streptomyces sp., and Rhodococcussp. One of the homologs from Oryza minuta protein OmBBD was reported to exhibit DNase and RNAse activity in vitro [1]. However, other studies have failed to detect similar activity in Cor or AtBBD1/ATBDD2 [2]. OmBBD carries a C-terminal UvrB domain that is absent in the mycobacterial sequences. UvrB is one component of the UvrABC endonuclease system. Hence it was proposed that OmBBD's observed nuclease activity may come not from this domain but from an interaction of the C-terminal UvrB with the catalytic UvrC nuclease [3].
