  • High specificity homocysteinases and genes therefor
    Patent number: 6140102
    Abstract: Novel enzymatic methods to determine the concentration of homocysteine in biological fluids are described. In a typical embodiment of the invention, the biological fluid sample is from a patient, and the methods of the invention are useful to assess risk for cardiovascular disease. The novel methods of the invention involve use of particular homocysteinase enzymes that permit the determination of homocysteine concentrations in biological samples without interference from the concentrations of cysteine and/or of methionine that are routinely present in such samples. There is also provided a diagnostic kit for use in determining the amount of homocysteine in a biological sample comprising (a) a homocysteinase having the aformentioned characteristics, and (b) at least one reagent capable of being used to determine the amount of product formed in the homocysteinase reaction.
