Before revision:  In E. coli, the analysis of how pathways are entangled through essential plasticity and redundancy supports the view that synthetic lethality affects preferentially a single function or pathway , although with a major exception which unveils Cell Envelope Biosysthesis as an essential backup to Membrane Lipid Metabolism.
