Pyrroloquinoline quinone (PQQ) biosynthesis is complicated by the fact that it is synthesized in the cytoplasm and must then find its way to the periplasm where the active enzyme/cofactor complex is assembled. Clearly the a-nitrogen of tyrosine was n

In 2010, when the National Alliance for Advanced Biofuels and Bioproducts (NAABB) consortium began, little was known about the molecular basis of algal biomass or oil production. Very few algal genome sequences were available and efforts to identify

Malyl CoA lyase (MCL) is an Mg 2+ dependent enzyme that catalyzes the reversible cleavage of (2S) 4 malyl CoA to yield acetyl CoA and glyoxylate. MCL enzymes, which are found in a variety of bacteria, are members of the citrate lyase like family and

The 1,3-dithiane is a protected formaldehyde anion equivalent that could serve as a useful labeled synthon. We report a facile synthesis of 1,3-[2-13C]- and 1,3-[2-13C, 2-2H2]dithiane in two steps from [13C]- or [13C, 2H3]methyl phenyl sulfoxide. We
