Title: WHEAT GERM ACID PHOSPHATASE
Post by: brennanc on September 10, 2017, 09:54:43 PM

Assume that wheat germ acid phosphatase (mw 55,000; pHI=7.4) requires an aspartic acid residue (pK 4.5) and a histidine residue (pK 6.0) for activity.  What is the percentage of maximal activity still present at pH 7.2 (cellular pH)

You have to show your attempts at solving the problem to get help, this is the forum policy, as described in the forum rules (http://www.chemicalforums.com/index.php?topic=65859.0).

You must have found an equation in your textbook that covers this case.  That would be a good start.
