-!- Acts on RNA-DNA hybrids.
2.7.7.49
RNA-directed DNA polymerase.
based on mapping to UniProt P03362
Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
-!- Catalyzes RNA-template-directed extension of the 3'-end of a DNA strand by one deoxynucleotide at a time. -!- Cannot initiate a chain de novo. -!- Requires a RNA or DNA primer. -!- DNA can also serve as template. -!- See also EC 2.7.7.7.
3.1.-.-
