the folates with shorter glutamate chain lengths in bacteria cultured in the presence of adenine resulted from primary regulation of the de novo purine biosynthetic pathway , regulation which caused an accumulation of formyltetrahydropteroyl-poly-gamma-glutamates ( folate derivatives that are ineffective substrates for folylpolyglutamate synthetases ) , and did not result from regulation of folylpolyglutamate synthetase per se .
