The reaction between CH 3 CN and HCOOH: A possible chemical process of Alanine formation in interstellar medium Abstract Radical -radical and radical-neutral inter-action schemes are very important for the formation of comparatively complex molecules in low temperature chem-istry. An attempt has been...
W.L. and H.G. conducted part of the synthesis experiments and the bioactivity studies; K.D. and H.H. carried out computational studies of the reaction mechanism; S.Y. and B.-A.S. directed the bioactivity studies. Y.R.C. conceptualized and directed the project and drafted the manuscript...
The conversion rates of each reaction have been shown. The concentration of each protein was provided; GTP: 200 µM; c-di-GMP: 100 µM. CHASE4-PASPAC: IsmP1-413. b Growth of WT, ΔismP, and the complemented strain (ΔismP/p-ismP) in the presence or absence of iron (eeM...
