|1M54: Cystathionine-Beta Synthase: Reduced Vicinal Thiols |
reference: Human cystathionine beta-synthase is a heme sensor protein. Evidence that the redox sensor is heme and not the vicinal cysteines in the CXXC motif seen in the crystal structure of the truncated enzyme., Taoka S, Lepore BW, Kabil O, Ojha S, Ringe D, Banerjee R, Biochemistry 2002 Aug 20;41(33):10454-61.
