2.7.6.3 bifunctional protein 6-hydroxymethyl-7,8-dihydroxypterin pyrophosphokinase/7,8-dihydropteroate synthase is involved in tetrahydrofolate expressed in Escherichia coli 639684 2.7.6.3 expressed in Escherichia coli BL21 cells 723522 2.7.6.3 expressed in Escherichia coli BL21(DE3) cells 721193 2.7.6.3 expression in Escherichia coli 642764, 662800, 671307, 675392 2.7.6.3 expression in Escherichia coli and Saccharomyces cerevisiae 674784 2.7.6.3 expression of His6-tagged enzyme in Escherichia coli 671307 2.7.6.3 expression of His6-tagged maltose-binding-protein fusion HPPK in Escherichia coli strain BL21(DE3) 695332 2.7.6.3 expression of the bifunctional 6-hydroxymethyl-7,8-dihydropterin diphosphokinase/dihydropteroate synthase in Escherichia coli 662648 2.7.6.3 gene folK, sequence comparisons, recombinant expression of His6-tagged and maltose-binding-protein-tagged enzyme in Escherichia coli strain BL21-CodonPlus(DE3)-RIL 738210 2.7.6.3 hydroxymethyldihydropterin diphosphokinase from Plasmodium falciparum complements a folK-knockout mutant in Escherichia coli when expressed as a separate polypeptide detached from dihydropteroate synthase. Hydroxymethyldihydropterin diphosphokinase part of the bifunctional protein can function by itself but that a larger part of the polypeptide is needed to ensure full functionality 662804
