Lv. Gening et al., DETERMINATION OF HOMOSERINE KINASE-ACTIVITY BY CHROMATOGRAPHIC-SEPARATION AND MEASUREMENT OF REACTION-PRODUCTS, Biochemistry, 59(8), 1994, pp. 923-928
The activity and kinetic characteristics of both purified and unpurifi
ed homoserine kinase can be determined by thin-layer and paper chromat
ography of labeled reaction products followed by measurement of radioa
ctivity of the spots. The procedure is simpler, more sensitive, and mo
re specific than the methods used to date.
