BfUbb inhibits growth. (A) Alignment of BfUbb with human ubiquitin, showing the extended N-terminal SpI signal sequence of BfUbb. (B) Agar spot assays displaying the sensitivity/resistance profiles of four B. fragilis strains exposed to B. fragilis CM11 with an empty vector or ubb in trans. (C) Agar spot assays showing inhibition activities of dilutions of synthesized 76-aa BfUbb against four sensitive strains and one resistant strain. (D) Agar spot assay showing sensitivity of B. fragilis strain 0878320-1 to BfUbb versus purified bovine ubiquitin.
