Deleting all mycoloyltransferase genes in Corynebacterium glutamicum abolishes arabinogalactan-bound mycolates and TDM while still producing TMM, yet causes severe cell division and morphogenesis defects.
- Why it matters: Mycoloyltransferases are essential in many Mycobacteriales, but paralogs have obscured which steps they control in the cell envelope and division machinery.
- What they did: The study systematically deleted all mycoloyltransferase-encoding genes in C. glutamicum, generating a Δmyts mutant, and compared its envelope composition and division phenotypes to a Δpks strain.
- The result: The Δmyts mutant failed to assemble a mycomembrane and showed pronounced cell aggregation plus very severe division and morphogenesis defects, indicating mycoloyltransferases are required for mycomembrane assembly and also for cell division independently of canonical mycolic acid transfer.
