Small protein Cgl2215 enhances phenolic tolerance by promoting MytA activity in Corynebacterium glutamicum.

ABSTRACT: Corynebacterium glutamicum is a promising chassis microorganism for the bioconversion of lignocellulosic biomass owing to its good tolerance and degradation of the inhibitors generated in lignocellulosic pretreatments. Among the identified proteins encoded by genes within the C. glutamicum genome, nearly 400 are still functionally unknown. Based on previous transcriptome analysis, we found that the hypothetical protein gene cgl2215 was highly upregulated in response to phenol, ferulic acid, and vanillin stress. The cgl2215 deletion mutant was shown to be more sensitive than the parental strain to phenolic compounds as well as other environmental factors such as heat, ethanol, and oxidative stresses. Cgl2215 interacts with C. glutamicum mycoloyltransferase A (MytA) and enhances its in vitro
