2.7.7.48 | nucleoside triphosphate + RNAn | the enzyme catalyzes in vitro the transcription of short single-stranded RNA and DNA molecules into precise complementary RNA copies up to the full length of these templates. The transcription of RNA-oligonicleotide templates and DNA-oligonucleotide templates is equally effective. Differences in transcription efficiency are found to depend on nucleotide sequence rather than on the RNA or DNA nature of the single-stranded nucleic acid. Double-stranded nucleic acids such as poly(A)*poly(U) and a double-stranded DNA 14-mer are not transcribed. The RdRP-directed transcription can be primed. The unprimed transcription starts preferentially at the 3'-terminal nucleotide of the template. The enzyme is capable of adding a single noncomplementary nucleotide to the 3'-terminus of about 50% of the runoff transcripts. AMP is preferred over GMP whereas CMP and UMP are terminally added at very low frequency | Solanum lycopersicum | diphosphate + RNAn+1 | - |
