Question

Histidine enzyme activity Km Kcat
hHDC 1880 +/- 150 0.10 +/- 0.01 1.73 +/-0.07
S354G hHDC2 620 +/-10 1.45 +/- 0.21 2.01+/-  0.04
a. When the researchers added 0.80 mM histidine to each reaction, what
percent of Vmax would have been reached by hHDC? By the S354G mutant?
how do i do this please

Answer 1

is this right V=[(Vmax)(S)]/[Km + S],
V=Vmax(0.8)/(0.10+0.8)

V=Vmax0.89
V max =89%

Answer 2

I knew how to do this. I forgot now. Lol. Sorry.

Answer 3

so you can help out lol
