ProteomicsMS/MS analysis of in-gel tryptic peptides of wild-type and mutants of glutamine amidotransferase from Methanocaldococcus jannaschii
A stable post-translational modification, succinimide (SNN), found in Methanocaldococcus jannaschii (Mj) glutamine amidotransferase (GATase) is shown to impart hyper-thermostability to the protein. To explore the role of neighbouring residues in enabling deamidation of Asn109 to SNN, intact protein ...

ProteomicsIntact protein mass analysis of wild-type and mutants of glutamine amidotransferase from Methanocaldococcus jannaschii
The glutamine amidotransferase (GATase) from Methanocaldococcus jannaschii (Mj) harbours a stable post-translational modification, succinimide (SNN). As shown from earlier studies, the spontaneous deamidation of Asn109 leading to the formation of stable SNN in MjGATase, imparts hyper-thermostability...

ProteomicsCross-linking mass spectrometry and integrative modelling of Methanocaldococcus jannaschii GMP synthetase
GMP synthetases are enzymes that catalyze the conversion of XMP to GMP. The two-subunit type GMP synthetases are composed of a glutamine amidotransferase (GATase) subunit that catalyzes the conversion of Gln to Glu and ammonia, and the ATP pyrophosphatase (ATPPase) subunit that catalyzes the formati...
