Surface Eroding, Semicrystalline Polyanhydrides via Thiol-Ene "Click" Photopolymerization.
Biomacromolecules 16 , 1650-9, (2015) Surface eroding and semicrystalline polyanhydrides, with tunable erosion times and drug delivery pharmacokinetics largely dictated by erosion, are produced easily with thiol-ene "click" polymerization. This strategy yields both linear and cross-linked network... |

Structure of the GcpE-HMBPP complex from Thermus thermophilius.
Biochem. Biophys. Res. Commun. 458(2) , 246-50, (2015) Isoprenoid biosynthesis in many bacteria, plant chloroplasts and parasitic protozoa but not in humans proceeds via the mevalonate independent 2-C-methyl-D-erythritol-4-phosphate (MEP) pathway. Its penultimate reaction step is catalyzed by (E)-1-hydroxy-2-meth... |
