    Summary
    Although a folE null mutant could not be made by Baba (2006), leading to its inclusion in the set of 303 essential genes, Klaus (2005) were able to construct a deletion mutation in folE. [More information is available at EcoGene: EG11375]. GTP cyclohydrolase I is an allosteric enzyme that catalyzes the first step in the biosynthesis of tetrahydrofolate . [More information is available at EcoCyc: EG11375].
