macA

Gene
macA
Protein
Macrolide export protein MacA
Organism
Escherichia coli O157:H7
Length
371 amino acids
Function
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. Confers resistance against macrolides (By similarity).
Similarity
Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family.

Protein
Macrolide export protein MacA
Organism
Escherichia coli (strain K12)
Length
371 amino acids
Function
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.

Protein
Maleylacetate reductase 1
Organism
Rhodococcus opacus
Length
357 amino acids
Function
Plays a major role in the degradation of chloroaromatic compounds by channeling maleylacetate and some of its substituted derivatives into the 3-oxoadipate pathway. This enzyme converts maleylacetate and 2-chloromaleylacetate with similar efficiencies.
Similarity
Belongs to the iron-containing alcohol dehydrogenase family.
