The C-proteinase that processes procollagens to fibrillar collagens is identical to the protein previously identified as bone morphogenic protein-1.

Li, S W, Sieron, A L, Fertala, A, Hojima, Y, Arnold, W V, Prockop, D J

Bone morphogenic protein-1 (BMP-1) was originally identified as one of several BMPs that induced new bone formation when implanted into ectopic sites in rodents. BMP-1, however, differed from other...

Partial rescue of a lethal phenotype of fragile bones in transgenic mice with a chimeric antisense gene directed against a mutated collagen gene.

Khillan, J S, Li, S W, Prockop, D J

Previously, transgenic mice were prepared that developed a lethal phenotype of fragile bones because they expressed an internally deleted mini-gene for the pro alpha 1(I) chain of human type I...

Dissimilatory Reduction of Fe(III) and Other Electron Acceptors by a Thermus Isolate

Kieft, T. L., Fredrickson, J. K., Onstott, T. C., Gorby, Y. A., Kostandarithes, H. M., Bailey, T. J., ...

A thermophilic bacterium that can use O2, NO3−, Fe(III), and S0 as terminal electron acceptors for growth was isolated from groundwater sampled at a 3.2-km depth in a South African gold mine. This...

Reduction of Fe(III), Cr(VI), U(VI), and Tc(VII) by Deinococcus radiodurans R1

Fredrickson, J. K., Kostandarithes, H. M., Li, S. W., Plymale, A. E., Daly, M. J.

Deinococcus radiodurans is an exceptionally radiation-resistant microorganism capable of surviving acute exposures to ionizing radiation doses of 15,000 Gy and previously described as having a...

Effect of Electron Donor and Solution Chemistry on Products of Dissimilatory Reduction of Technetium by Shewanella putrefaciens

Wildung, R. E., Gorby, Y. A., Krupka, K. M., Hess, N. J., Li, S. W., Plymale, A. E., ...

To help provide a fundamental basis for use of microbial dissimilatory reduction processes in separating or immobilizing 99Tc in waste or groundwaters, the effects of electron donor and the presence...

Isolation and Characterization of a Subsurface Bacterium Capable of Growth on Toluene, Naphthalene, and Other Aromatic Compounds

Fredrickson, J. K., Brockman, F. J., Workman, D. J., Li, S. W., Stevens, T. O.

A bacterium, designated F199, utilized toluene, naphthalene, dibenzothiophene, salicylate, benzoate, p-cresol, and all isomers of xylene as a sole carbon and energy source. This bacterium was...

Intact Soil-Core Microcosms for Evaluating the Fate and Ecological Impact of the Release of Genetically Engineered Microorganisms

Bentjen, S. A., Fredrickson, J. K., Van Voris, P., Li, S. W.

Intact soil-core microcosms were studied to determine their applicability for evaluating the transport, survival, and potential ecosystem effects of genetically engineered microorganisms before they...

Enumeration of Tn5 mutant bacteria in soil by using a most- probable-number-DNA hybridization procedure and antibiotic resistance.

Fredrickson, J K, Bezdicek, D F, Brockman, F J, Li, S W

Investigations were made into the utility of DNA hybridization in conjunction with a microdilution most-probable-number procedure for the enumeration of Rhizobium spp. and Pseudomonas putida in soil....

Plasmid Incidence in Bacteria from Deep Subsurface Sediments

Fredrickson, J. K., Hicks, R. J., Li, S. W., Brockman, F. J.

Bacteria were isolated from deep terrestrial subsurface sediments underlying the coastal plain of South Carolina. A total of 163 isolates from deep sediments, surface soil, and return drill muds were...

Microbiological Degradation of Organic Components in Oil Shale Retort Water: Organic Acids

Rogers, J. E., Riley, R. G., Li, S. W., Mann, D. C., Wildung, R. E.

The losses of benzoic acid and a homologous series of both mono- and dibasic aliphatic acids in oil shale retort water were monitored with time (21 days) in liquid culture (4% retort water, vol/vol)...

Phosphorothioate and cordycepin analogues of 2',5'-oligoadenylate: inhibition of human immunodeficiency virus type 1 reverse transcriptase and infection in vitro.

Montefiori, D C, Sobol, R W, Li, S W, Reichenbach, N L, Suhadolnik, R J, Charubala, R, ...

Natural antiviral activity can be mediated by the interferon-induced synthesis of 2',5'-oligoadenylates (2-5As) and subsequent RNase L activation by these molecules. Analogues of 2-5A that are...

Synthesis of recombinant human procollagen II in a stably transfected tumour cell line (HT1080).

Fertala, A, Sieron, A L, Ganguly, A, Li, S W, Ala-Kokko, L, Anumula, K R, ...

Apparently because the biosynthetic pathways involve eight or more highly specific post-translational enzymes, it has been difficult to obtain expression of genes for fibrillar collagens in...
