Discovery of Superior Enzymes by Directed Molecular Evolution
ChemBioChem, 2001 Natural selection has created optimal catalysts that exhibit their convincing performance even with a number of sometimes counteracting constraints. Optimal performance of enzyme catalysis does not refer necessarily to maximum reaction rate. Rather, it may involve a compromise between specificity, rate, stability, and other chemical constraints ; in ...

Improving glyphosate oxidation activity of glycine oxidase from Bacillus cereus by directed evolution. [PDF]
PLoS ONE, 2013 Glyphosate, a broad spectrum herbicide widely used in agriculture all over the world, inhibits 5-enolpyruvylshikimate-3-phosphate synthase in the shikimate pathway, and glycine oxidase (GO) has been reported to be able to catalyze the oxidative ...

Transport of fullerene molecules along graphene nanoribbons [PDF]
, 2012 We study the motion of C60 fullerene molecules (buckyballs) and short-length carbon nanotubes on graphene nanoribbons. We demonstrate that the nanoribbon edge creates an effective potential that keeps the carbon structures on the surface.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Hematopoietic (stem) cells—The elixir of life?
FEBS Letters, EarlyView.The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

BMC Evolutionary Biology, 2010 Background Conger eel galectins, congerin I (ConI) and congerin II (ConII), show the different molecular characteristics resulting from accelerating evolution. We recently reconstructed a probable ancestral form of congerins, Con-anc.

Molecular Bio-imprinting of Biocatalysts [PDF]
, 2011 Energy conservation is the cry of the day. Attempts are made all over the world to occupy and use energy reserves. Increased industrialization and mechanization has led to the depletion of natural energy reserves. Its unavoidable to search for renewable

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
