Evolutionary dynamics determines adaptation to inactivation of an essential gene [PDF]

arXiv, 2019
Genetic inactivation of essential genes creates an evolutionary scenario distinct from escape from drug inhibition, but the mechanisms of microbe adaptations in such cases remain unknown. Here we inactivate E. coli dihydrofolate reductase (DHFR) by introducing D27G,N,F chromosomal mutations in a key catalytic residue with subsequent adaptation by ...

Raman-assisted crystallography reveals end-on peroxide intermediates in a nonheme iron enzyme [PDF]

Science, American Association for the Advancement of Science, 2007, pp.449-53, 2014
Iron-peroxide intermediates are central in the reaction cycle of many iron-containing biomolecules. We trapped iron(III)-(hydro)peroxo species in crystals of superoxide reductase (SOR), a nonheme mononuclear iron enzyme that scavenges superoxide radicals.
