AbstractAbstract PDF
The Gram-reaction-negative, strictly aerobic, non-motile, nonspore- forming, and rod-shaped bacterial strain designated BS11T was isolated from the compost and its taxonomic position was investigated by using a polyphasic approach. Strain BS11T grew optimally at 30?7캜 and at pH 7.0 in the absence of NaCl on nutrient agar. Strain BS11T displayed ?glucosidase activity that was responsible for its ability to transform ginsenoside Rb1 (one of the dominant active components of ginseng) to Rd. On the basis of 16S rRNA gene sequence similarity, strain BS11T was shown to belong to the family Sphingomonadaceae and was related to Sphingosinicella vermicomposti YC7378T (96.3% sequence similarity), S. xenopeptidilytica 3-2W4T (96.2%), S. microcystinivorans Y2T (96.1%), and S. soli KSL-125 T (95.9%). The G+C content of the genomic DNA was 64.9%. The major menaquinone was Q-10 and the major fatty acids were summed feature 7 (comprising C18:1 ?c/?t/?2t; 40.6%), C16:0 (22.5%), C17:1 ?c (13.7%) and C17:0 (9.1%). DNA and chemotaxonomic data supported the affiliation of strain BS11T to the genus Sphingosinicella. Strain BS11T could be differentiated genotypically and phenotypically from the recognized species of the genus Sphingosinicella. The novel isolate therefore represents a novel species, for which the name Sphingosinicella ginsenosidimutans sp. nov. is proposed, with the type strain BS11T (=KACC 16619T =JCM 18201T).

AbstractAbstract PDF
The focus of this study was the cloning, expression, and characterization of recombinant ginsenoside hydrolyzing β-glucosidase from Arthrobacter chlorophenolicus with an ultimate objective to more efficiently bio-transform ginse-nosides. The gene bglAch, consisting of 1,260 bp (419 amino acid residues) was cloned and the recombinant enzyme, over-expressed in Escherichia coli BL21 (DE3), was characterized. The GST-fused BglAch was purified using GST·Bind agarose resin and characterized. Under optimal conditions (pH 6.0 and 37°C) BglAch hydrolyzed the outer glucose and arabino-pyranose moieties of ginsenosides Rb1 and Rb2 at the C20 position of the aglycone into ginsenoside Rd. This was fol-lowed by hydrolysis into F2 of the outer glucose moiety of ginsenoside Rd at the C3 position of the aglycone. Additio-nally, BglAch more slowly transformed Rc to F2 via C-Mc1 (compared to hydrolysis of Rb1 or Rb2). These results in-dicate that the recombinant BglAch could be useful for the production of ginsenoside F2 for use in the pharmaceutical and cosmetic industries.

AbstractAbstract PDF
Aminopeptidases are metalloproteinases that degrade N-terminal residues from protein and play important roles in cell growth and development by controlling cell homeostasis and protein maturation. We determined the crystal structure of XoLAP, a leucyl aminopeptidase, at 2.6 Å resolution from Xanthomonas oryzae pv. oryzae, causing the destructive rice disease of bacterial blight. It is the first crystal structure of aminopeptidase from phytopathogens as a drug target. XoLAP existed as a hexamer and the monomer structure consisted of an N-terminal cap domain and a C-terminal peptidase domain with two divalent zinc ions. XoLAP structure was compared with BlLAP and EcLAP (EcPepA) structures. Based on the structural comparison, the molecular model of XoLAP in complex with the natural aminopeptidase inhibitor of microginin FR1 was proposed. The model structure will be useful to develop a novel antibacterial drug against Xoo.

AbstractAbstract PDF
A Gram-reaction-negative, strictly aerobic, non-motile, nonspore-forming, and rod-shaped bacterial strain designated KHI28T was isolated from sediment in Gapcheon (river) and its taxonomic position was investigated using a polyphasic approach. Strain KHI28T grew at 10–42°C and at pH 5.5–8.5 on R2A and nutrient agar without additional NaCl as a supplement. Strain KHI28T possessed β-glucosidase activity, which was responsible for its ability to transform ginsenosides Rb1 and Re (ones of the dominant active components of ginseng) to C-K and Rg2, respectively. On the basis of 16S rRNA gene sequence similarity, strain KHI28T was shown to belong to the family Sphingobacteriaceae and to be related to Mucilaginibacter dorajii DR-f4T (97.9% sequence similarity), M. polysacchareus DRP28T (97.3%), and M. lappiensis ANJLI2 T (97.2%). The G+C content of the genomic DNA was 45.8%. The predominant respiratory quinone was MK-7 and the major fatty acids were summed feature 3 (comprising C16:1 ω6c and/or C16:1 ω7c), iso-C15:0 and C16:0. DNA and chemotaxonomic data supported the affiliation of strain KHI28T to the genus Mucilaginibacter. Strain KHI28T could be differentiated genotypically and phenotypically from the recognized species of the genus Mucilaginibacter. The isolate therefore represents a novel species, for which the name Mucilaginibacter ginsenosidivorax sp. nov. is proposed, with the type strain KHI28T (=KACC 14955T =LMG 25804T).
