Guanosine Diphosphate 122-125 H3 histone pseudogene 16 Homo sapiens 170-173 8329399-3 1993 When GTP gamma S is substituted for GDP in cellular N-ras p21, the chemical shifts of resonances Asp-47, -126, -154, and Asn-172, as well as Gly-77 and -151, are not sensitive to nucleotide exchange, whereas Asp-30, -33, -38, -54, -57, -69, -92, -105, and -119 are affected. Guanosine Diphosphate 36-39 H3 histone pseudogene 16 Homo sapiens 58-61
