Glycerol kinase is suitable for clinical diagnostic use in levels of neutral fat. Glycerol kinase from Cellulomonas sp. NT3060 shows good stability against several preservatives such as N-methylisothiazolone and imidazolidinylurea. We have cloned glpK gene from Cellulomonas sp. NT3060. This glpK gene is composed of 1,518 bp nucleotides and encodes 505 amino acid residues. The glpK gene was expressed in Escherichia coli and Cellulomonas sp. glycerol kinase was purified to homogeneity by column chromatography. The glycerol kinase exhibited high tolerance to various preservatives compared to other glycerol kinases. This tolerance was found to be favorable feature as diagnostic reagent for quantity of triglyceride.
