Sulfacytine is a competitive inhibitor of the enzyme dihydropteroate synthetase. It inhibits bacterial synthesis of of dihydrofolic acid by preventing the condensation of the pteridine with para-aminobenzoic acid (PABA), a substrate of the enzyme dihydropteroate synthetase. The inhibited reaction is necessary in these organisms for the synthesis of folic acid."""@en ; dct:identifier "drugbank:DB01298" ; dct:title "Sulfacytine"@en ; adv:Drug ; rdfs:label "Sulfacytine [drugbank:DB01298]"@en ; rdfs:seeAlso <http://www.drugbank.ca/drugs/DB01298> . }
