Vitamin K (VK), a fat-soluble vitamin, functions as a co-factor during the gamma-carboxylation reaction that converts glutamic acid residues to gamma-carboxyglutamic acid residues in proteins transiting through the endoplasmic reticulum. Two enzymes are involved which together form the VK cycle: gam...

Vitamin K (VK) is a micronutrient required for the gamma-carboxylation of secreted proteins. Clinical studies have recently implicated VK in the pathophysiology of diabetes. Our data indicate that rodent beta-cells lacking gamma-carboxylation fail to adapt their insulin secretion in response to gluc...

Histone H3 monoaminylations at glutamine(Q) 5 represent an important family of epigenetic markers in neurons that play critical roles in the mediation of permissive gene expression (1, 2). We previously demonstrated that H3Q5 serotonylation(ser) and dopaminylation(dop) are catalyzed by the Transglut...
