Protein citrullination results from enzymatic deimination of peptidylarginine and plays an important role in health and disease. Despite increasing scientific interest, the identity and function of citrullinated proteins in vivo remain widely unknown. Thorough proteomic studies could contribute to a

We report the esterification of the carboxyl groups of the cyclic peptide toxins nodularin-R and microcystin-LA to produce stable diacetoxymethyl and dipropionyloxymethyl ester derivatives. The derivatives had no activity but were reactivated upon esterase treatment. When injected into cells, the

The reaction of phenylglyoxal, a reagent specific for arginine residues, with erythrocyte membrane at pH 7.4 results in complete inhibition of sulfate equilibrium exchange across human red cells. The inactivation was found to be concentration and time dependent. The binding

We demonstrated that aluminum (Al)-induced oxalate secretion and plasma membrane (PM) H(+)-ATPase activity in tomato (Lycopersicon esculentum 'Hezuo903') roots were poorly correlated. In addition, vanadate, an inhibitor of PM H(+)-ATPase, had no effect on Al-induced oxalate secretion, but significantly inhibited
