ABSTRACT
|
|
|
| |
|
The crystal structure of a high oxygen affinity species of hemoglobin,
bar-headed goose hemoglobin in deoxy form, has been determined to a resolution
of 2.8 A. The R and R(free) factor of the model are 0.197 and 0.243,
respectively. The structure reported here is a special deoxy state of hemoglobin
and indicates the differences in allosteric mechanisms between the goose and
human hemoglobins. The quaternary structure of the goose deoxy hemoglobin shows
obvious differences from that of human deoxy hemoglobin. The rotation angle of
one alphabeta dimer relative to its partner in a tetramer molecule from the
goose oxy to deoxy hemoglobin is only 4.6 degrees, and the translation is only
0.3 A, which are much smaller than those in human hemoglobin. In the
alpha(1)beta(2) switch region of the goose deoxy hemoglobin, the imidazole ring
of His beta(2)97 does not span the side-chain of Thr alpha(1)41 relative to the
oxy hemoglobin as in human hemoglobin. And the tertiary structure changes of
heme pocket and FG corner are also smaller than that in human hemoglobin. A
unique mutation among avian and mammalian Hbs of alpha119 from proline to
alanine at the alpha(1)beta(1 )interface in bar-headed goose hemoglobin brings a
gap between Ala alpha119 and Leu beta55, the minimum distance between the two
residues is 4.66 A. At the entrance to the central cavity around the molecular
dyad, some residues of two beta chains form a positively charged groove where
the inositol pentaphosphate binds to the hemoglobin. The His beta146 is at the
inositol pentaphosphate binding site and the salt-bridge between His beta146 and
Asp beta94 does not exist in the deoxy hemoglobin, which brings the weak
chloride-independent Bohr effect to bar-headed goose hemoglobin.

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.
