| Definition | Enacyloxin IIa is structurally distinct but acts in a similar mechanism to kirromycin-like elfamycins. It prohibits the transfer of the amino acid at the A site to the elongating peptide chain. It is most likely that the mechanism of action is that EF-Tu*GDP is locked in the EF-Tu*GTP form, and EF-Tu*GDP*aa-tRNA is immobilized on the ribosome. It is an open question whether enacyloxin IIa actually belongs to the kirromycin-like group of elfamycins due to their high similarity. |
