Systematically Engineering for Efficient Production of 3‐Methyl‐1‐Butanol in Escherichia coli
Advanced Science, EarlyView.An integrated metabolic engineering strategy was established for high‐level 3‐methyl‐1‐butanol biosynthesis in Escherichia coli. Molecular dynamics‐guided semi‐rational engineering of dihydroxyacid dehydratase uncovered and relieved key catalytic bottlenecks, while adaptive laboratory evolution enhanced strain robustness.

4-(4-Nitrobenzyl)morpholine [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 In the title compound, C(11)H(14)N(2)O(3), an inter-molecular inter-action between a nitro group O atom and a neighboring benzene ring helps to stabilize the crystal structure [N⋯centroid = 3.933 (2) Å]. No classical hydrogen bonds are observed in the crystal packing.
