N - acetylhexosamine - dehydrogenase, a process for their preparation, a method for quantitative analysis of n - acetyl glucosamine or n - acetyl galactosamine with the use of the same, as well as a kit for the quantitative analysis

摘要

it is a acetylhexosamin dehydrogenase is provided which hydrogen of n - or n - acetylglucosamin acetylgalactosamin away, this n - or n - acetylgalactosaminolacton acetylglucosaminolacton to convict, and at the same time, coenzyme nad + to nadh reduced.the present invention $a, the enzyme can be obtained by a strain of the genus pseudomonas, and an ability to produce n - acetylhexosamin dehydrogenase has, in a medium breeds for the enzyme from the cultured product wins.also provided is a $a procedure for quantitative analysis of n - acetylglucosamin or n acetylgalactosamin and n - acetylglucosamin dehydrogenase on a sample containing n - or n - acetylgalactosamin acetylglucosamin influence is and the quantity of the resulting nadh attaches.
