Project description:We investigated the effect of canavanine (toxic Arg analogue) treatment on U251MG and U87MG cell lines using a variety of methods including proteomics. Since 3rd isotope of unmodified peptide cannot be resolved from canavanine containing peptide even at extremely high resolutions of 480K we incorporated R13C615N4 into peptides to avoid MS1 overlap of Arg signals.
Project description:We treated C. albicans reference strain SC5314 with 20ng/ml of aureobasidin A, and obtained two mutants which were resistant to aureobasidin A. Then we did whole genome sequencing of these two mutants.
Project description:Corynebacterium glutamicum strain ATCC 21831 is a producer of L-arginine that was created by random mutagenesis. It is resistant to the arginine structural analogue canavanine. In order to identify potential bottlenecks in the biosynthetic pathway that leads to this industrially important amino acid, relative metabolite abundances of biosynthetic intermediates were determined in comparison to the type strain ATCC 13032. An extract of U13C-labeled biomass was used as internal standard, to correct for different ionization efficiencies. Metabolites were identified using the ALLocator web platform.
