Moreover, we could detect human GS web site 2 (S8) phosphorylation by mass spectrometry for The 1st time inside a recombinant enzyme planning. Collectively, these final results demonstrate that expression in insect cells is ample to accomplish phosphorylation at several inhibitory web pages and to supply acceptable enzyme preparations to review in

Comparisons in between human, C. elegans and yeast GS constructions are consistent with the human framework from the inactive point out. Each human GS protomer exhibits a shut conformation of its Lively web site, along with a regulatory loop that only becomes purchased on G6P binding is disordered during the human structure (Supplementary Fig. 8a,
