Secretome characterization of clinical isolates from the Mycobacterium abscessus complex provides insight into antigenic differences

tailieu.vn

Interestingly and in line with the in- creased secretome size as compared to MTB, the KEGG pathway analysis showed a high abundance of the Quorum sensing pathway for the predicted MAB secre- tomes, which was not present in our previous MTB secretome pathway analysis [19]. The InterPro annotation showed that Mce domains were the most abundant (2.14%) domains in the MAB reference secretome, while PPE and PE-PGRS domains only corresponded to 0.3% of the ES protein sequences..
