PMID: 24201963
Plant Cell Rep. 1993 Oct;12(12):676-80. doi: 10.1007/BF00233418.

Organogenesis of shoots of bell pepper (Capsicum annuum L.) was achieved in fourteen cultivars on Murashige and Skoog's medium (MS medium) supplemented only with 0.4% (w/v) Gellan gum (pH 5.8). Mature seeds of cv. Shinsakigake-2 were sown on filter...

Flexible Enantiodivergent Synthesis and Biological Activity of Mannostatin Analogues, New Cyclitol Glycosidase Inhibitors.

The Journal of organic chemistry

PMID: 11666964
J Org Chem. 1996 Jan 26;61(2):480-488. doi: 10.1021/jo951126v.

Mannostatin A (1) is a new cyclitol inhibitor of glycoprotein processing. 2-Epimannostatin A (12) and its enantiomer (13) as well as their positional isomers (14, 15) were designed for probing structure-activity relationships in this class of glycosidase inhibitors. The...

The architecture of windmill hexameric zinc(II) -porphyrin array 1 is attractive as a light-harvesting functional unit in view of its three-dimensionally extended geometry that is favorable for a large cross-section of incident light as well as for a suitable...

Phosphorus-carbon bond formation by lewis Acid catalyzed/mediated addition of silylphosphines.

The Journal of organic chemistry

Hayashi M, Matsuura Y, Nishimura Y, Yamasaki T, Imai Y, Watanabe Y.
PMID: 17784776
J Org Chem. 2007 Sep 28;72(20):7798-800. doi: 10.1021/jo701330q. Epub 2007 Sep 05.

Triethylaluminum-catalyzed/mediated addition of a silylphosphine to aldehydes and epoxides is described. Organophosphines containing a silyloxy group at the alpha- or beta-position on the alkyl substituent are successfully prepared in good yields.

Identification of an insertion sequence, IS1203 variant, in a Shiga toxin 2 gene of Escherichia coli O157:H7.

Journal of bioscience and bioengineering

Kusumoto M, Nishiya Y, Kawamura Y, Shinagawa K.
PMID: 16232431
J Biosci Bioeng. 1999;87(1):93-6. doi: 10.1016/s1389-1723(99)80014-0.

An insertion sequence composed of 1310 bp was found in Shiga toxin 2 genes of some isolates of Escherichia coli O157:H7. This insertion sequence showed extremely high homology with IS1203 of E. coli O111:H(-). This IS1203 variant was inserted...

Spontaneous reactivation of Shiga toxins in Escherichia coli O157:H7 cells caused by transposon excision.

Journal of bioscience and bioengineering

IS1203v is an insertion sequence which has been found in inactivated Shiga toxin 2 genes (stx2) of Escherichia coli O157:H7. Using PCR amplification, we detected the wild-type stx2 genes in colonies of E. coli O157:H7 which possessed stx2 genes...

Host-dependent activation of IS1203v excision in Shiga toxin-producing Escherichia coli.

Journal of bioscience and bioengineering

IS1203v is an insertion sequence (IS) which is identical to the most abundant IS elements in the genome of Escherichia coli O157:H7. However, there is no sequence homologous to IS1203v in the genome of E. coli K-12. We constructed...
