bacterial isoleucine synthesis pathway

Post by MrMistery » Fri Oct 20, 2006 6:01 pm

Ok, so i was reading biology today during my french class, and i stumbled upon feedback inhibition as a gene expression mechanism in prokaryotes. as an example, they had the isoleucine synthesis from threonine, when isoleucine inhibits the treonindezaminase enzyme. All good, except i noticed something there that seemed very very strange. on of the intermediate products was called alpha-ketoisoleucine.
How can you have a keto group bound to the alpha carbon of the aminoacid? what would the structure of this coumpound look like? isn't that what the alpha at the beginning stands for?
