Guanosine Diphosphate 65-68 H3 histone pseudogene 16 Homo sapiens 0-3 8318164-5 1993 We have previously constructed the three-dimensional structure of the p21 protein bound to GDP from an available alpha-carbon tracing of this protein using a combination of molecular dynamics and energy minimization (Dykes, et al., J. Biomol. Guanosine Diphosphate 91-94 H3 histone pseudogene 16 Homo sapiens 70-73 8318164-9 1993 In this communication we compare our computed structure for the p21-GDP complex to this x-ray crystal structure. Guanosine Diphosphate 68-71 H3 histone pseudogene 16 Homo sapiens 64-67 8318164-15 1993 Both of these regions have been found in x-ray crystallographic studies of p21-GDP and p21-GTP complexes to undergo significant changes in conformation upon the binding of GTP in place of GDP to the protein. Guanosine Diphosphate 79-82 H3 histone pseudogene 16 Homo sapiens 75-78 8318164-15 1993 Both of these regions have been found in x-ray crystallographic studies of p21-GDP and p21-GTP complexes to undergo significant changes in conformation upon the binding of GTP in place of GDP to the protein. Guanosine Diphosphate 188-191 H3 histone pseudogene 16 Homo sapiens 75-78 8318164-15 1993 Both of these regions have been found in x-ray crystallographic studies of p21-GDP and p21-GTP complexes to undergo significant changes in conformation upon the binding of GTP in place of GDP to the protein.
