CommentsRv3131, (MTCY03A2.27c), len: 332 aa. Conserved protein, similar to other hypothetical bacterial proteins e.g. O53476|Rv2032|MTV018.19 (331 aa), FASTA scores: opt: 568, E(): 2.5e-27, (36.7% identity in 321 aa overlap); O05800|Rv3127|MTCY164.37 (344 aa), FASTA scores: opt: 521, E(): 1.9e-24, (34.95% identity in 326 aa overlap); Q9RI33|SCJ12.27c from Streptomyces coelicolor (335 aa), FASTA scores: opt: 441, E(): 1.3e-19, (35.75% identity in 319 aa overlap); Q9RI44|SCJ12.14 from Streptomyces coelicolor (309 aa), FASTA scores: opt: 328, E(): 9.3e-13, (27.9% identity in 308 aa overlap); Q9CBP5|ML1751 from Mycobacterium leprae (721 aa), FASTA scores: opt: 137, E(): 0.78, (26.15% identity in 298 aa overlap); etc. Equivalent to AAK47555 from Mycobacterium tuberculosis strain CDC1551 but shorter 12 aa. Predicted possible vaccine candidate (See Zvi et al., 2008).
