General Information | Comment | Organism |
---|---|---|
malfunction | enzyme mutants exhibit strikingly altered cell wall permeability, leading to a marked increase in susceptibility to lipophilic antibiotics and the host antimicrobial molecules defensing and lysozyme. The predominant chain lengths are 2-4 carbons shorter for oxygenated mycolates in the absence of the enzyme | Mycobacterium tuberculosis |
physiological function | enzyme-dependent mycolate elongation is essential for cording and cell wall impermeability. Enzyme-dependent cell wall impermeability is essential for antibiotic resistance. The enzyme is essential for resistance to macrophage antimicrobial activity | Mycobacterium tuberculosis |
