Kinetic measurements of phosphoglucose isomerase and phosphomannose isomerase by direct analysis of phosphorylated aldose–ketose isomers using tandem mass spectrometry

International Journal of Mass Spectrometry, 2005
Abstract A mass spectrometry based method for the direct determination of kinetic constants for phosphoglucose isomerase (PGI) and phosphomannose isomerase (PMI) is described. PGI catalyzes the interconversion between glucose-6-phosphate (Glc6P) and fructose-6-phosphate (Fru6P) and PMI performs the same function between mannose-6-phosphate (Man6P ...

Mechanism for aldose-ketose interconversion by d-xylose isomerase involving ring opening followed by a 1,2-hydride shift

Journal of Molecular Biology, 1990
The active site and mechanism of D-xylose isomerase have been probed by determination of the crystal structures of the enzyme bound to various substrates, inhibitors and cations. Ring-opening is an obligatory first step of the reaction and is believed to be the rate-determining step for the aldose to ketose conversion. The structure of a complex with a

Crystal Structure of YihS in Complex with d-Mannose: Structural Annotation of Escherichia coli and Salmonella enterica yihS-encoded Proteins to an Aldose–Ketose Isomerase

Journal of Molecular Biology, 2008
The three-dimensional structure of a Salmonella enterica hypothetical protein YihS is significantly similar to that of N-acyl-D-glucosamine 2-epimerase (AGE) with respect to a common scaffold, an alpha6/alpha6-barrel, although the function of YihS remains to be clarified. To identify the function of YihS, Escherichia coli and S.

9 Aldose-Ketose Isomerases

1972
Publisher Summary This chapter describes the molecular and catalytic properties of aldose–ketose isomerases. Aldose–ketose isomerases catalyze the interconversion of isomeric aldo- and keto sugars by causing the migration of carbon-bound hydrogen between carbons 1 and 2.
