Nucleophilic Substitution at the Guanidine Carbon Center via Guanidine Cyclic Diimide Activation

open access: yesOrganic Letters, 2021
Despite the electron-deficient nature of the guanidine carbon centers, nucleophilic reactions at these sites have been underdeveloped because of the resonance stabilization of the guanidine group.

Widespread bacterial utilization of guanidine as nitrogen source

open access: yesMolecular Microbiology, 2021
Guanidine is sensed by at least four different classes of riboswitches that are widespread in bacteria. However, only very few insights into physiological roles of guanidine exist.

Discovery and characterization of a fourth class of guanidine riboswitches

open access: yesNucleic Acids Research, 2020
Riboswitches are RNAs that specifically sense a small molecule and regulate genes accordingly. The recent discovery of guanidine-binding riboswitches revealed the biological significance of this compound, and uncovered genes related to its biology.

Biochemical Validation of a Second Guanidine Riboswitch Class in Bacteria

open access: yesBiochemistry, 2017
Recently, it was determined that representatives of the riboswitch candidates called ykkC and ykkC-III directly bind free guanidine. Guanidine-binding ykkC motif RNAs, now renamed guanidine-I riboswitches, were demonstrated to commonly regulate the ...
