  ABSTRACT  
 
F(420)-dependent secondary alcohol dehydrogenase (Adf) from methanogenic archaea is a member of the growing bacterial luciferase family which are all TIM barrel enzymes, most of which with an unusual nonprolyl cis peptide bond. We report here on the crystal structure of Adf from Methanoculleus thermophilicus at 1.8 A resolution in complex with a F(420)-acetone adduct. The knowledge of the F(420) binding mode in Adf provides the molecular basis for modeling F(420) and FMN into the other enzymes of the family. A nonprolyl cis peptide bond was identified as an essential part of a bulge that serves as backstop at the Re-face of F(420) to keep it in a bent conformation. The acetone moiety of the F(420)-acetone adduct is positioned at the Si-face of F(420) deeply buried inside the protein. Isopropanol can be reliably modeled and a hydrogen transfer mechanism postulated. His39 and Glu108 can be identified as key players for binding of the acetone or isopropanol oxygens and for catalysis.

Figure 4. The Nonprolyl cis Peptide Bond in AdfThe nonprolyl cis peptide bond between Cys72 and Ile73 is an essential constituent of a bulge that is directed toward the F[420] binding site, causing a bent conformation of the deazaisoalloxazine ring. The well-conserved Asp38, which would partly interfere with a straight course of strand b3, is strongly linked to the polypeptide chain and stabilizes the bulge. These favorable interactions might compensate for the energy lost when forming the nonprolyl cis peptide bond.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
