- ATP + a [protein]-(L-amino acyl-L-serine) <=> ADP + phosphate + a [protein]-(S,S)-2-(C-substituted-aminomethyl)-4-acyl-2-oxazoline
- ATP + a [protein]-(L-amino acyl-L-threonine) <=> ADP + phosphate + a [protein]-(S,S)-2-(C-substituted-aminomethyl)-4-acyl-5-methyl-2-oxazoline
- ATP + a [protein]-(L-amino acyl-L-cysteine) <=> ADP + phosphate + a [protein]-(1S,4R)-2-(C-substituted-aminomethyl)-4-acyl-2-thiazoline
- Requires Mg(2+).
- The enzyme, which participates in the biosynthesis of ribosomal
peptide natural products (RiPPs), converts L-cysteine, L-serine and
L-threonine residues to thiazoline, oxazoline, and methyloxazoline
- The enzyme requires two domains - a cyclodehydratase domain, known as
a YcaO domain, and a substrate recognition domain (RRE domain) that
controls the regiospecificity of the enzyme.
- The RRE domain can either be fused to the YcaO domain or occur as a
separate protein; however both domains are required for activity.
- The enzyme can process multiple residues within the same substrate
peptide, and all enzymes characterized so far follow a defined order,
starting with the L-cysteine closest to the C-terminus.
- The reaction involves phosphorylation of the preceding ribosomal
peptide backbone amide bond, forming ADP and a phosphorylated
intermediate, followed by release of the phosphate group.
- In some cases the enzyme catalyzes a side reaction in which the
phosphorylated intermediate reacts with ADP to form AMP and
