Splet01. sep. 2024 · During “short-patch” BER, only the single missing nucleotide is replaced by POLβ [14]. However, a sub-pathway denoted long-patch repair also exists in which POlβ (and/or possibly POLδ) insert multiple nucleotides, thereby displacing a 5’-single-strand flap that is subsequently removed by FEN1 endonuclease (Fig. 1 e) [15, 16]. Spletshort-patch BER was monitored as a function of time (Figure 3). Repair products were analysed by autoradiography after electrophoretic separation in denaturing 15% PAGE.
