WebThanks to its chemical plasticity, cysteine (Cys) is a very versatile player in proteins. A major determinant of Cys reactivity is pKa: the ability to predict it is deemed critical in redox bioinformatics. I considered different computational methods for pKa predictions and ultimately applied one (p … WebIn the fat body, FMRFa signaling promoted lipolysis by increasing PKA and lipase activity. In sweet-sensing gustatory neurons, FMRFa signaling suppressed appetitive perception and hence food intake. We also demonstrated that dietary cysteine worked in a similar way in mice via neuropeptide FF (NPFF) signaling, a mammalian RFamide peptide.
