N-Methyl-D-aspartate (NMDA) receptors mediate excitatory synaptic transmission in the central nervous system and play important roles in synaptic development and plasticity, but also mediate glutamate neurotoxicity. Recently, 2-naphthoic acid (NPA) and its derivatives have been identified as allosteric, noncompetitive NMDA...

The large pool of cytochrome P450 (P450) open-reading frames identified in genome sequences has attracted much attention as a resource for new oxidation biocatalysts. P450 genes were cloned from genome-sequenced bacteria and coexpressed with putidaredoxin and its reductase genes to...
