what's your favorite standard DNA nucleobase? protein-templated DNA synthesis expanding our understanding of the central dogma. video sources: Clockwork - The INCREDIBLE new way bacteria are defending against viruses, NanoRooms This physics rule built biology’s language. Here’s how. | EoB Ch1, yourgenome From DNA to protein - 3D, MG Lomb 3D & interactive Molecular Motor 4k "Defense-associated reverse transcriptases (DRTs) are widespread bacterial anti-phage systems that use unconventional mechanisms of polynucleotide synthesis. We show that DRT3, which comprises two distinct RTs (Drt3a and Drt3b) and a noncoding RNA (ncRNA), synthesizes alternating poly(GT/AC) double-stranded DNA. Cryo–electron microscopy structures at 2.6 Å resolution reveal a D3-symmetric 6:6:6 complex of Drt3a, Drt3b, and ncRNA. Drt3a produces the poly(GT) strand using a conserved ACACAC template within the ncRNA. Notably, Drt3b synthesizes a complementary, protein-primed poly(AC) strand in the complete absence of a nucleic acid template, using conserved active site residues specific to Drt3b to enforce precise base alternation. These findings expand the functional landscape of nucleic acid polymerases, revealing a protein-templated mechanism for sequence-specific DNA synthesis." Deng P, Lee H, Armijo C, Wang H, Gao A.
