Study of the intestinal tyrosine metabolism using stable isotopes and gas chromatography-mass spectrometry.
TLDR
The intestinal flora showed activities for decarboxylation leading to phenol and p-cresol, dehydroxylation lead to phenylpropionic acid and rearrangement leading to 3-hydroxyphenyl Propionic acid. Expand
Secretion of tyrosinase in Streptomyces glaucescens.
In Streptomyces glaucescens, the intracellular and the extracellular enzyme forms of tyrosinase were found to be indentical in molecular weight (29 000), in copper content (0.21%), in the 19 aminoExpand
INFLUENCE OF THE CONCENTRATION OF BRANCHED CHAIN AMINO ACIDS ON THE FORMATION OF FUSEL ALCOHOLS
The influence of concentrations of branched-chain amino acids on the total, anabolic and catabolic production of isobutyl, active amyl, and isoamyl alcohol by Saccharomyces cerevisiae X 2180-1A hasExpand

Vasari tells us that Bramante was so anxious to see quick progress at St. Peter's that he destroyed many fine papal tombs, thereby obliterating the memory of great men whose memorials were to beExpand
Cytochrome Difference Spectra of Acetic Acid Bacteria
TLDR
Within the genus Acetobacter, the Peroxydans group of Frateur could be separated through its cytochrome d content from the Oxydans and Mesoxydan groups. Expand
Influence of glucose on adenine nucleotide levels and energy charge in Acetobacter aceti
TLDR
During the inhibition of growth by glucose in the glucose sensitive mutant, three phases could be distinguished: a first period with a transient decline in the total adenine nucleotide level and no change in the energy charge, followed by a second period after ethanol exhaustion characterized by a lower totalAdenineucleotide level in the presence of glucose and a lower energy charge.

Characterization of the acetyl-CoA synthetase of Acetobacter aceti.
The acetate activating system of Acetobacter aceti has been studied. The enzyme responsible, acetyl-CoA synthetase, has been purified about 500-fold from crude cell extracts and was approximately 85%Expand
A Note on Raphael's Sibyls in S. Maria della Pace
