6-hydroxymethyl-7,8-dihydropterin + 4-aminobenzoate = 7,8-dihydropteroate + H2O
6-hydroxymethyl-7,8-dihydropterin + 4-aminobenzoate = 7,8-dihydropteroate + h2o
6-hydroxymethyl-7,8-dihydropterin + 4-aminobenzoate = 7,8-dihydropteroate + H2O
6-hydroxymethyl-7,8-dihydropterin + 4-aminobenzoate = 7,8-dihydropteroate + h2o
