4-methyleneglutamine synthetase: a new amide synthetase present in germinating peanuts.

Enzymatic activity which catalyzes the synthesis of 4-methyleneglutamine from 4-methyleneglutamic acid + ammonia was detected in and partially purified from cotyledons of peanut seeds germinated 5 to 7 days. This activity was separated from glutamine and asparagine synthetases by ammonium sulfate precipitation and DEAE-cellulose chromatography. The enzyme is distinct from these other amide synthetases in its substrate specificity, lack of amide/hydroxylamine exchange, and use of ammonium ion as amide donor together with formation of AMP from ATP. The activity is quite labile in solution, but is retained as a precipitate in ammonium sulfate or when frozen in 12.5% glycerol at -77 degrees C. This activity might be responsible for catalyzing the rapid synthesis of 4-methyleneglutamine which occurs in germinating peanuts. << Less
