“…On the other hand, the expression of GPM1 is constitutive (Rodicio et al, 1993). In the case of enolase, expression of ENO1 is constitutive, but the expression of ENO2 is glucose-inducible (Cohen et al, 1986;Cohen et al, 1987;McAlister and Holland, 1985). However, in our wild-type strain 2845, the Glc : GL ratios of Pgk, Gpm, Eno, Pyk and Zwf (a control non-glycolytic enzyme) enzyme activities were 1.05, 1.27, 2.20, 2.46 and 0.70, respectively (Table 5, lines 1-3).…”
