Synthesis and biological evaluation of asiatic acid derivatives as inhibitors of glycogen phosphorylases
Other topics include the activities of a-amylases in the presence of polyethylene glycols, color and polysaccharide content in sugarcane and sugarbeet juice, and phosphorylases
in the production of oligosaccharides.
A third analysis involves comparison of proteins altered post-translationally after toxicant exposure with specific gene transcript changes in kinases, proteases, phosphorylases
, conjugating enzymes, and other enzymes that target specific proteins for modification.
The enzymes that can do this include the glucosyltransferases, such as phosphorylases
that elongate amylopectin side chains, and branching enzymes that increase the number of branching points.
were extracted following the methods used for amylase and activity measured as described by Steup and Latzko (1979).
The Seattle researchers found that kinases ferry certain chemical subunits, called phosphate groups, from the energy-rich molecule ATP to dormant phosphorylases
Glycosylation of carboxylic group: A new reaction of sucrose phosphorylases
But it's possible to create new or enhanced functionalities for starch by enzymatically changing its structural properties using glucosyltransferases, such as phosphorylases
and branching enzymes.
Fosphenytoin itself has no pharmacological activity but is dephosphorylated in vivo by phosphorylases
to the active drug, phenytoin.
