    Also known as
    ECK2760; sscR; ygcM
    Summary
    QueD was mistakenly identified as a 6-pyruvoyl tetrahydrobiopterin (PPH4) synthase (PTPS); the identity of the product was not confirmed (Woo, 2002). [More information is available at EcoGene: EG13120]. SscR has been demonstrated in vitro to be a working 6-pyruvoyl tetrahydropterin synthase . [More information is available at EcoCyc: G7431].
