Glucarate dehydratase

GLYCOGEN PHOSPHORYLASE 1,3-y3-G LUCAN SYNTHASE GLUCARATE DEHYDRATASE D-Glucitol,... [Pg.745]

The stereochemistry of /1-elimination reactions catalysed by D-galactonate dehydratase (GalD) and D-glucarate dehydratase (GlucD) enzymes is apparently not dictated by the pKas of the 7-protons of the carboxylate anion substrates.74 It had been observed previously that enzyme-catalysed dehydration initiated by abstraction of the a-proton (P a > 29) from a carboxylate anion substrate usually proceeds via anti elimination, whereas syn elimination occurs when the proton is a- to an aldehyde, ketone, or thioester and correspondingly more acidic (pKa < 25). [Pg.380]
