Glycoregulation of E3(SCF) ubiquitin ligases in unicellular eukaryotes
Skp1 is an essential adaptor within the Skp1/Cul1/F-box (SCF) class of E3 polyubiquitin ligases that regulate protein degradation in all eukaryotes. Skp1 is also a target of a 5-enzyme glycosylation pathway in parasites and other unicellular eukaryotes. Glycosylation of Skp1 is contingent upon oxygen-dependent hydroxylation of a critical Pro residue by a homolog of the …
