Universal scaling relation and criticality in metabolism and growth of Escherichia coli [PDF]
Phys. Rev. Research 6, 013035 (2024), 2023 The metabolic network plays a crucial role in regulating bacterial metabolism and growth, but it is subject to inherent molecular stochasticity. Previous studies have utilized flux balance analysis and the maximum entropy method to predict metabolic fluxes and growth rates, while the underlying principles governing bacterial metabolism and growth ...

Construction of Escherichia coli K-12 in-frame, single-gene knockout mutants: the Keio collection
Molecular Systems Biology, 2006 We have systematically made a set of precisely defined, single‐gene deletions of all nonessential genes in Escherichia coli K‐12. Open‐reading frame coding regions were replaced with a kanamycin cassette flanked by FLP recognition target sites by using a

The long polar fimbriae (lpf) operon and its flanking regions in bovine Escherichia coli O157:H43 and STEC O136:H12 strains [PDF]
, 2013 Long polar fimbriae (Lpf) are intestinal adhesins and important virulence factors of pathogenic Escherichia coli strains. We cloned and sequenced the lpf2-1 operon (lpf2ABCD) and its flanking regions of an intimin- and Shiga toxin-negative E.
