Abstract
|
|
|
A very short hydrogen bond between an Asp and a phosphate is established in two
high resolution structures (0.98 and 1.05 A). A mutant complex that changes the
Asp to an Asn, which forms a normal hydrogen bond, has a similar free energy of
binding to the wild type complex, suggesting that the contribution of the short
hydrogen bond is not extraordinarily strong.
