    Abstract: The present disclosure provides compositions and methods to increase the percentage of edited cells in a cell population when employing nucleic-acid guided editing, as well as automated multi-module instruments for performing these methods. Specifically, the disclosure relates to methods, compositions, modules and automated multi-module cell processing instruments that increase the efficiency of nucleic acid-guided editing in a cell population using a nucleic acid nuclease (i.e., an RNA-guided nuclease or “RGN”)/single-strand binding protein (“SSB”) fusion system. The system leverages a single-strand binding protein (SSP) and single-strand DNA annealing protein (“SSAP”) interactions to drive enhanced recruitment.
