a
The plus symbol indicates that a gene was previously annotated (18) and/or identified through performing a translated nucleotide database search using an E. coli K-12 (57) or B. subtilis 168 (58) query in tBLASTn (59), performed at the Comprehensive Microbial Resource website (60). The minus symbol indicates that no homolog was detected (RNase E, RNase II, and RNase J2). B. subtilis RNase J1 (555 amino acids) and B. burgdorferi B31 PhnP (762 amino acids) share homology of 124 amino acids (BLAST score, 73; identities, 31/124; positives, 54/124), indicated by +/−.
