| + | [https://www.uniprot.org/uniprot/MACA_ECOLI MACA_ECOLI] Part of the tripartite efflux system MacAB-TolC. MacA stimulates the ATPase activity of MacB by promoting the closed ATP-bound state of MacB, increases the capacity of MacB to bind macrolides such as erythromycin, and provides a physical link between MacB and TolC. When overexpressed, the system confers resistance against macrolides composed of 14- and 15-membered lactones but no or weak resistance against 16-membered ones. In addition, MacA binds tightly rough-core lipopolysaccharide (R-LPS), suggesting that the system could also transport R-LPS or a similar glycolipid.<ref>PMID:11544226</ref> <ref>PMID:17214741</ref> <ref>PMID:18955484</ref> <ref>PMID:21696464</ref> <ref>PMID:23974027</ref> | ||
