Fractionation of the pyruvate oxidase of Proteus vulgaris.
Cell-free extracts of Proteus vulgar& oxidize pyruvate to acetate and COS. By acid precipitation of such extracts, Stumpf (1) prepared a protein fraction that required cocarboxylase and certain divalent metal ions for activity; no requirement for phosphate or other acetyl acceptor system could be demonstrated. Thus the system resembled that of Escherichia coli described by Still (2), and differ...
متن کاملBacteriophage typing of Proteus mirabilis, Proteus vulgaris, and Proteus morganii.
A bacteriphage typing scheme for differentiating Proteus isolated from clinical specimens was developed. Twenty-one distinct patterns of lysis were seen when 15 bacteriophages isolated on 8 Proteus mirabilis, 1 P. vulgaris, and 1 P. morganii were used to type 162 of 189 (85.7%) P. mirabilis and P. vulgaris isolates. Seven phages isolated on 3 P. morganii were used to type 13 of 19 (68.4%) P. mo...
متن کاملAcyloin condensation reactions of pyruvic oxidase.
Almost all enzymes capable of decarboxylating pyruvate have been shown to catalyze DPT’-dependent condensation reactions yielding acyloins such as AMC (l-7). Recent work of Schweet and coworkers (8) has demonstrated that in animal tissues these condensations are due to the activity of pyruvic oxidase. Purified preparations of pyruvic oxidase from pigeon breast muscle have the same ratio of acyl...
متن کاملIdentification of Proteus penneri sp. nov., formerly known as Proteus vulgaris indole negative or as Proteus vulgaris biogroup 1.
The name Proteus penneri sp. nov. is proposed for a group of organisms previously called Proteus vulgaris indole negative or P. vulgaris biogroup 1. All of these strains were salicin negative, esculin negative, and chloramphenicol resistant (zone size, less than 14 mm). DNA relatedness studies indicated that when DNA from P. penneri strain 1808-73 was labeled and tested against unlabeled DNA fr...
متن کاملIsolation of phenylalanine-negative Proteus vulgaris.
Three phenylalanine-negative Proteus vulgaris strains were isolated from three different sources. The significance of these Proteus strains has not been fully recognized.
