Stress induces tRNA cleavage by angiogenin in mammalian cells.

abstract：:Moloney murine leukemia virus reverse transcriptase (RT) selectively uses deoxyribonucleotides over ribonucleotides (rNTPs) as substrates. Substitution of F155 with valine (F155V) was previously found to increase the enzyme's affinity for rNTPs, though without affecting the V(max) for catalysis, and thereby conferred ...
