Klenow vs Klentaq DNA Polymerase: Strand Orientation Comparison #1404149 (License: Personal Use)

The image illustrates two DNA polymerase fragments-Klenow (blue) and Klentaq (red/orange)-positioned along a nucleic acid ruler marked 5' to 3'. Klenow exhibits an asymmetric binding mode with distinct 5' and 3' ends, while Klentaq displays symmetry, indicating its engineered thermostable properties. Both are shown with active sites aligned to the 3' hydroxyl for nucleotide addition, highlighting functional conservation despite structural divergence.
