enzyme solution exhibits absorption maxima at 279 and 415 nm, and the ratio of absorbance value at 415 nm to that at 279 nm i 0.158
pyridoxal 5'-phosphate
dependent on, best at 0.025-0.1 mM in whole-cell assay
pyridoxal 5'-phosphate
PLP, binding structure and binding mode, overview. The highly flexible active site contributes to the low affinity for pyridoxal 5'-phosphate in SrLDC. The cofactor affinity is increased in enzyme mutant A225C/T302C due to introduction of an artificial disulfide bond
pyridoxal 5'-phosphate
PLP, binding structure and binding mode, overview. The PLP cofactor binds mainly to the pocket formed at the barrel domain, and the catalytic residue Lys51 interacts with the aldehyde group of the pyridoxal ring. The pyridine ring is stabilized by hydrogen bond between N1 of the ring and the acidic residue Glu255. The phosphate moiety of PLP is mainly stabilized by strong hydrogen bonds with the side-chains of His179, Ser182, and Tyr352, and the main chains of Gly219, Gly257, and Arg258 are also involved in the stabilization of the moiety
