ABSTRACT
|
|
|
|
| |
|
|
The replacement of aspartic acid by histidine at position 153 in Escherichia
coli alkaline phosphatase results in a mutant enzyme that is remarkably similar
to certain mammalian alkaline phosphatases that are activated by magnesium in a
time-dependent fashion. These mammalian alkaline phosphatases have histidine at
the position corresponding to 153 of the E. coli sequence. Here we report the
three-dimensional structure of the mutant E. coli alkaline phosphatase with
histidine at position 153. The structure reveals that the octahedral magnesium
binding site has been converted to a tetrahedral zinc binding site with an
imidazole ring nitrogen of His-153 as one of the ligands to the zinc. The
alteration in metal binding caused by the mutation could explain the origin of
the magnesium activation observed with the mammalian alkaline phosphatases. The
structure also reveals differences in the mode of phosphate binding, explaining
the enhanced phosphate affinity and the reduced activity of the mutant enzyme in
the presence of zinc.

Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
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.
