Product Name 3-[(4R)-4-hydroxycyclohexa-1,5-dien-1-yl]-2-oxopropanoate isomerase
Example Structure Example Structure of 3-[(4R)-4-hydroxycyclohexa-1,5-dien-1-yl]-2-oxopropanoate isomerase EC#: 5.3.3.19
Synonyms BacB
EC Number 5.3.3.19
CAS Registry Number
Comments The enzyme, characterized from the bacterium?Bacillus subtilis, is involved in the biosynthesis of the nonribosomally synthesized dipeptide antibiotic bacilysin, composed of?L-alanine and?L-anticapsin. The enzyme can interconvert the (E) isomer formed in the reaction into the (Z) isomer [2], although this isomerization is not part of the pathway leading to bacilysin [3].
