α-L-Fucosidases are key enzymes for the degradation of intestinal glycans by gut microbes. In this work, three putative α-L-fucosidases (Afc1, Afc2, and Afc3) genes from Clostridium perfringens ATCC 13124 were cloned and expressed in Escherichia coli. Afc1 had the α-L-fucosidase domain of glycoside hydrolase (GH) 29 family but showed no enzyme activity(More)
We report here the first observation of photoluminescence from single CdSe quantum confined nanorods (quantum rods). Luminescence imaging spectra of individual rods were obtained for two samples, with average aspect ratio of 2 and 4, respectively. Typical room-temperature luminescence spectral line widths of the rods in both samples are less than 60meV,(More)
Antitubulin chemotherapeutics agents, such as paclitaxel, are effective chemotherapy drugs for cancer treatment. However, painful neuropathy is a major adverse effect limiting the wider application of chemotherapeutics. In this study, we found that A-kinase anchor protein 150 (AKAP150) was significantly upregulated after paclitaxel injection. Inhibition of(More)
Antimicrotubulin chemotherapeutic agents such as vincristine (VCR), often induce peripheral neuropathic pain. It is usually permanent and seriously harmful to cancer patients' quality of life and can result in the hampering of clinical treatments. Currently, there is no definitive therapy, and many of the drugs approved for the treatment of other(More)
UNLABELLED β-N-Acetylhexosaminidases have attracted interest particularly for oligosaccharide synthesis, but their use remains limited by the rarity of enzyme sources , low efficiency, and relaxed regioselectivity of transglycosylation. In this work, genes of 13 β-N-acetylhexosaminidases, including 5 from Bacteroides fragilis ATCC 25285, 5 from Clostridium(More)
