FIG. 1.

(a) Comparison of the hrcA locus in B. breve UCC 2003 with corresponding loci in various other actinobacteria. Each arrow indicates an open reading frame. The length of arrows is proportional to the length of the predicted open reading frames. Corresponding genes are marked with the same color or pattern. The putative function of the proteins is indicated above each arrow (see text for explanation). Black arrows indicate hypothetical open reading frames. The amino acid identity with respect to B. breve UCC 2003 protein sequences is indicated as a percentage. (b) Alignment of the amino acid sequence for DnaJ₂ proteins from gram-positive bacteria. CE, Corynebacterium efficiens YS-314; MT, Mycobacterium tuberculosis H37Rv; SC, Streptomyces coelicolor A3; BL, B. longum NCC 2705; BB, B. breve UCC 2003; BS, B. subtilis. The various conserved amino acid regions are indicated and explained in the text.
