應用
Glycerokinase from Cellulomonas sp. has been used:
- for determining the kinetic characteristics of human and trypanosomatid phosphofructokinases using an enzyme-linked kinetic assay.
- to study the effect of sugar in fluorescence emission.
- in 2-Arachidonoylglycerol-based fluorescence assay for DH-463, a fluorescent activity-based probe for monoacylglycerol lipase.
生化/生理作用
甘油激酶催化甘油的tge MgATP依赖性磷酸化以产生sn-甘油-3-磷酸,并且是甘油利用中的限速酶。 它也受到果糖-1,6-二磷酸的反馈调节。
