Bacterial evolution by intelligent design.


:In a process called quorum sensing, bacteria produce and secrete certain signaling compounds (called autoinducers) that bind to receptors on other bacteria and activate transcription of certain genes. A clever genetic selection yields a new quorum-sensing transcriptional regulator that marches to the beat of a different drummer.

  • Reaction mechanism of N-acetylneuraminic acid lyase revealed by a combination of crystallography, QM/MM simulation, and mutagenesis.

    abstract::N-Acetylneuraminic acid lyase (NAL) is a Class I aldolase that catalyzes the reversible condensation of pyruvate with N-acetyl-d-mannosamine (ManNAc) to yield the sialic acid N-acetylneuraminic acid (Neu5Ac). Aldolases are finding increasing use as biocatalysts for the stereospecific synthesis of complex molecules. In...
