Conversion units for kcat/km

[angelkissesH]

Hello,

 

I'm trying to convert a kcat/km obtained from a journal article from s-1*uM-1 to s-1*M-1.

 

kcat = .55 s-1

Km = 71.7 uM

kcat/km = .008 s-1*M-1

 

I'm assuming that I just need to convert the 71.7 uM into M (.0000717M) and then divide to get the value 7670 s-1*M-1

 

However, and older, much respected labmate claims the value should be 4.8 E5 in his notes.

 

Am I doing my math wrong?

 

Thanks!!!

I turns out they were converting it to min-1 * M-1 not s-1* M-1.

 

Thanks!!
