label: rDNA spacer replication fork barrier binding, bending
label_lc: rdna spacer replication fork barrier binding, bending
description: "The activity of binding selectively, and in a sequence-specific manner, a replication fork barrier found in rDNA spacers, and distorting the original structure of DNA, typically a straight helix, into a bend, or increasing the bend if the original structure was intrinsically bent due to its sequence."
