Congressman Frank Pallone, Jr. Applications due November In plants, AHAS performs the first step in synthesis of three essential amino acids, making it an effective target for herbicides.

Sparsomycin contacts primarily a P-site bound substrate, but also extends into the active-site hydrophobic crevice. Virginiamycin M occupies portions of both the A and P-site, and induces a conformational change in the ribosome.

The acetyl group of the latter, which is a substrate both in vivo and in vitro, could potentially bind in a similar position to the 1-hydroxyl of chloramphenicol, in close proximity to the side chain of Leu In the case of Gln CAT, large increases in Km for the three acetyl acceptors were accompanied by small decreases in kcat and in apparent affinity for acetyl-CoA.
Such results are consistent with the introduction of the relatively hydrophilic amide in place of the delta-methyl groups of Leu The kinetic properties of Phe CAT were unexpected in that Km for each of the three acetyl acceptors was unchanged or reduced, compared to the equivalent parameters for the wild-type enzyme, whereas kcat fell significantly fold in each case.
As the residue substitutions for Leu do not result in enhanced discrimination against the binding and acetylation of 1-acetylchloramphenicol, it appears unlikely that the 1-acetyl group binds to the CAT active site in the same position as that occupied by the 1-hydroxyl of chloramphenicol.
