Effect of Temperature on Saprophytic Cryptococci: Observations Relating to Wall Biosynthesis at Non-permissive Growth Temperatures

Autor: K. F. Conant, R. O. Burns, R. Dabbagh

Publikováno v: Journal of General Microbiology. 85:190-202

Summary: An attempt was made to define the basis of temperature-induced aberrant wall biosynthesis in Cryptococcus diffluens. A quantitative determination of the sulphydryl content of the cell surface of C. diffluens as an index of a protein disulphi

Transcriptional activity of the transposable element Tn10 in the Salmonella typhimurium ilvGEDA operon

Autor: R. O. Burns, Dale L. Blazey

Publikováno v: Proceedings of the National Academy of Sciences. 79:5011-5015

Polarity of Tn10 insertion mutations in the Salmonella typhimurium ilvGEDA operon depends on both the location and the orientation of the Tn10 element. One orientation of Tn10 insertions in ilvG and ilvE permits low-level expression of the downstream

Molecular cloning and expression of the ilvGEDAY genes from Salmonella typhimurium

Autor: R Kim, R O Burns, D L Blazey

Publikováno v: Journal of Bacteriology. 147:452-462

The ilvGEDAY genes of Salmonella typhimurium were cloned in Escherichia coli K-12 by in vitro recombination techniques. A single species of recombinant plasmid, designated pDU1, was obtained by selecting for Valr Ampr transformants of strain SK1592.

Effect of Temperature on Saprophytic Cryptococci: Temperature-induced Lysis and Protoplast Formation

Autor: R. O. Burns, N. F. Conant, R. Dabbagh, H. S. Nielsen

Publikováno v: Journal of General Microbiology. 85:177-189

Summary: The saprophytic cryptococci, Cryptococcus diffluens, Cryptococcus laurentii and Cryptococcus albidus which are characterized by inability to grow at 37 °C and above, were shown to lyse at non-permissive growth temperatures. Incorporation of

Gene ilvY of Salmonella typhimurium

Autor: D L Blazey, R O Burns

Publikováno v: Journal of Bacteriology. 142:1015-1018

Evidence is presented for the existence in Salmonella typhimurium LT2 of the regulatory gene ilv Y. The Escherichia coli K-12 ilvY gene product is shown to complement a S. typhimurium ilvY mutation in vivo.

Protection Against Hypertension, Arteriolonecrosis and Death by Hog Renal Extracts in Experimental Malignant Hypertension

Autor: R. O. Burns, George E. Wakerlin

Publikováno v: Circulation Research. 1:454-459

Since hog renin is effective in the treatment and prophylaxis of chronic experimental renal hypertension in the dog, probably through antirenin, a study was made of the prophylactic effect of crude and semipurified hog renins from cortex and from who
