摘要：

The atomic models of the complex between rbonuclease I both in the ATP and ADP forms have been determined byo X-ray analysis at an effective resolution of 2.8 Å and 3 Å, respectively. The two structures are very similar. The actin molecule consists of two domains which can be further subdivided into two subdomains. ADP or ATP is located in the cleft between the domains with a calcium ion bound to the β- or β- and γ-phosphates, respectively. The motif of a five-stranded (3 sheet consisting of a (3 meander and a right handed βαβ unit appears in each domain suggesting that gene duplication might have occurred. These sheets have the same topology as that found in hexokinase. © 1990 Nature Publishing Group.
