Structural and functional analyses of the echinomycin resistance conferring protein Ecm16 from Streptomyces lasalocidi.

Echinomycin is a natural product DNA bisintercalator antibiotic. The echinomycin biosynthetic gene cluster in Streptomyces lasalocidi includes a gene encoding the self-resistance protein Ecm16. Here, we present the 2.

The UvrA-like protein Ecm16 requires ATPase activity to render resistance against echinomycin.

Bacteria use various strategies to become antibiotic resistant. The molecular details of these strategies are not fully understood. We can increase our understanding by investigating the same strategies found in antibiotic-producing bacteria.
