1 We have now demonstrated that minus strand synthesis is strongly repressed upon the binding of eEF1A.GTP to the valylated viral RNA. Guanosine Triphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
2 Higher eEF1A.GTP levels were needed to repress minus strand synthesis templated by valyl-EMV TLS RNA, which binds eEF1A.GTP with lower affinity than does valyl-TYMV RNA. Guanosine Triphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
3 Higher eEF1A.GTP levels were needed to repress minus strand synthesis templated by valyl-EMV TLS RNA, which binds eEF1A.GTP with lower affinity than does valyl-TYMV RNA. Guanosine Triphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
4 Higher eEF1A.GTP levels were needed to repress minus strand synthesis templated by valyl-EMV TLS RNA, which binds eEF1A.GTP with lower affinity than does valyl-TYMV RNA. Guanosine Triphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
5 Higher eEF1A.GTP levels were needed to repress minus strand synthesis templated by valyl-EMV TLS RNA, which binds eEF1A.GTP with lower affinity than does valyl-TYMV RNA. Guanosine Triphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
6 Repression by eEF1A.GTP was also observed with a methionylated variant of TYMV RNA and with aminoacylated tRNAHis, tRNAAla, and tRNAPhe transcripts. Guanosine Triphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
7 It is proposed that minus strand repression by eEF1A.GTP binding occurs early during infection to help coordinate the competing translation and replication functions of the genomic RNA. Guanosine Triphosphate eukaryotic translation elongation factor 1 alpha 1 Homo sapiens
