  • Process for preparing acyl-CoA synthetase LCF-18
    Patent number: 4269942
    Abstract: Acyl-CoA synthetase, having a high activity to C.sub.16 -C.sub.18 long chain fatty acids, is obtained by cultivating Pseudomonas aeruginosa IFO 3919. Pseudomonas aeruginosa IFO 3919 can produce acyl-CoA synthetase LCF-18 in large quantities, and the acyl-CoA synthetase LCF-18 produced by Pseudomonas aeruginosa IFO 3919 is very stable in storage.

  • Process for preparing acyl-CoA synthetase LCF-18
    Patent number: 4229538
    Abstract: Acyl-CoA synthetase, having a high activity to C.sub.16 -C.sub.18 long chain fatty acids, is obtained by culturing strains belonging to various genera. As is known, acyl-CoA synthetase, having a strong activity to C.sub.16 -C.sub.18 long chain fatty acids, is generally obtained from liver of rat; however, it has now been discovered that acyl-CoA synthetase can be obtained from microorganisms and this enzyme is called acyl-CoA synthetase LCF-18. By use of acyl-CoA synthetase LCF-18 of the present invention which has a high activity to C.sub.16 -C.sub.18 long chain fatty acids, serum non-esterified fatty acid of human beings can be accurately determined, and it is very useful for diagnosis of diabetes and so forth.
