The roots of Euphorbia kansui are considered an important traditional folk medicine. In this study the ethanol extracts of E. kansui were investigated. A new tetracyclic triterpenoid, euphane-3b,20-dihydroxy-24-ene, in addition to five known triterpenoids with euphane skeletons were isolated. Their structures were elucidated on the basis of physical and spectral techniques (1D-, 2D-NMR and MS, respectively).

Vitamin B(12) (cobalamin) is a dietary requirement for humans because it is an essential cofactor for two enzymes, methylmalonyl-CoA mutase and methionine synthase (METH). Land plants and fungi neither synthesize or require cobalamin because they do not contain methylmalonyl-CoA mutase, and have an alternative B(12)-independent methionine synthase (METE).

We have cloned and functionally characterized two Na(+)-coupled dicarboxylate transporters, namely ceNaDC1 and ceNaDC2, from Caenorhabditis elegans. These two transporters show significant sequence homology with the product of the Indy gene identified in Drosophila melanogaster and with the Na(+)-coupled dicarboxylate transporters NaDC1 and NaDC3 identified in mammals. In a mammalian cell heterologous expression system, the cloned ceNaDC1 and ceNaDC2 mediate Na(+)-coupled transport of various dicarboxylates.

MOTIVATION: A major challenge in post-genomic research has been to understand how physiological and pathological phenotypes arise from the networks of expressed genes. Here, we addressed this issue by developing an algorithm to mimic the behavior of regulatory networks in silico and to identify the dynamic response to disease and changing cellular conditions.

FAAH-like anandamide transporter (FLAT) regulates anandamide transport for hydrolysis and may be an attractive drug target for pain regulation. We aimed to discover potential FLAT antagonists from traditional Chinese medicine (TCM) using virtual screening, ligand-based drug design and molecular dynamics simulation (MD). Guineensine and Retrofractamide A exhibited high Dock Scores in FLAT.

Organisms growing at elevated temperatures face the challenge of maintaining the integrity of their genetic materials. Archaea possess unique chromatin proteins for gene organization and information processing. We present the solution structure of Sso7c4 from Sulfolobus solfataricus, which has a homodimeric DNA-binding fold forming a swapped β-loop-β 'Tai-Chi' topology. The fold is reminiscent of the N-terminal DNA-binding domain of AbrB and MazE.
