摘要:
The present invention relates to modified GTP cyclohydrolase II enzymes that display increased specific activity, and to polynucleotides encoding them. The invention further pertains to vectors comprising these polynucleotides and host cells containing such vectors. The invention provides a method for producing the modified enzyme and a method for producing riboflavin, a riboflavin precursor, FMN, FAD, or a derivative thereof.

摘要:
The invention relates to a method of finding suitable parameters for the chromatographic purification of biomolecules. The method consists of equilibration, charging, washing and eluting steps, this sequence of steps being carried out by the partial batch method. The parameters determined in small, preferably numerous parallel test batches provide conclusions as to the chromatography conditions under which a given biomolecule can be purified optimally by column chromatography, optionally even on a larger scale.
