Long-read DNA-Seq of SmAP1 knockout strains

Halobacterium salinarum knockout strains (delta-Ura3: control; delta-Ura3/delta-SmAP1: SmAP1 knockout) were cultured in uracil-supplemented (50 μg/mL) complex medium (CM) until mid-exponential phase (OD600nm = 0.5). The cultures were grown at 37C, under light exposure, and with constant agitation (125 RPM). We collected 2 mL samples and submitted them to DNA extraction using the DNeasy Blood &amp; Tissue kit (QIAGEN), according to the manufacturer's instructions for Gram-negative bacteria. We tested DNA samples for purity and quantity using spectrophotometric and fluorimetric methods, respectively. The samples were prepared for long-read sequencing following the 1D native barcoding genomic DNA protocol using SQK-LSK108 and EXP-NBD103 (Oxford Nanopore Technologies). The equimolar pool of barcoded samples was sequenced using a MinION Mk1B instrument (Oxford Nanopore Technologies) in an FLO-MIN106 flow cell for 24 hours. Three biological replicates were sequenced for each one of the strains (control and SmAP1 knockout). This repository stores the partitioned (eleven parts: aa-ak) compressed directory (tar.gz) containing all the raw reads (fast5 format) output by the MinKNOW software. <strong>Experimental design:</strong> <strong>Barcode</strong> <strong>Description</strong> Barcode 01 Control, biological replicate 1 Barcode 02 Control, biological replicate 2 Barcode 03 Control, biological replicate 3 Barcode 04 SmAP1 knockout, biological replicate 1 Barcode 05 SmAP1 knockout, biological replicate 2 Barcode 06 SmAP1 knockout, biological replicate 3 <strong>Instructions to merge files and extract:</strong> 1.
