ABSTRACT
|
|
|
| |
|
The interaction of native and Co(II)-substituted isozymes I and II of carbonic
anhydrase (CA) with histamine, a well-known activator, was investigated
kinetically, spectroscopically, and X-ray crystallographically. This activator
is of the noncompetitive type with 4-nitrophenyl acetate and CO2 as substrates
for both HCA I and HCA II. The electronic spectrum of the adduct of Co(II)-HCA
II with histamine is similar to the spectrum of the Co(II)-HCA II-phenol adduct,
being only slightly different from that of the uncomplexed enzyme. This is the
first spectroscopic evidence that the activator molecule binds within the active
site, but not directly to the metal ion. X-ray crystallographic data for the
adduct of HCA II with histamine showed that the activator molecule is bound at
the entrance of the active site cavity in a position where it may actively
participate in shuttling protons between the active site and the bulk solvent.
The role of the activators and the reported X-ray crystal structure of the HCA
II-histamine adduct has prompted us to reexamine the X-ray structures of the
different CA isozymes in order to find a structural basis accounting for their
large differences in catalytic rate. A tentative explanation is proposed on the
basis of possible pathways of proton transfer, which constitute the
rate-limiting step in the catalytic reaction.

only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
