Functional Characterization of Seven Γ-Glutamylpolyamine Synthetase
JOURNAL OF BACTERIOLOGY, Aug. 2011, p. 3923–3930 Vol. 193, No. 15 0021-9193/11/$12.00 doi:10.1128/JB.05105-11 Copyright © 2011, American Society for Microbiology. All Rights Reserved.

Tran- scriptome analysis in response to exogenous Put and Spd led to the identification of a list of genes encoding putative enzymes for the catabolism of polyamines. Among them, pauA1 to pauA6, pauB1 to pauB4, pauC, and pauD1 and pauD2 (polyamine utilization) encode enzymes homologous to Escherichia coli PuuABCD of the ␥-glutamylation pathway in converting Put into GABA. A series of unmarked pauA mutants was constructed for growth phenotype analysis. The results revealed that it requires specific combinations of pauA knockouts to abolish utilization of different polyamines and support the importance of ␥-glutamylation for polyamine catabolism in P. aeruginosa. Another finding was that the list of Spd-inducible genes overlaps almost completely with that of Put-inducible ones except the pauA3B2 operon and the bauABCD operon (-alanine utilization). -

In Arabidopsis five PAO genes (AtPAO1–AtPAO5) have been identified which present some common characteristics, but also important dif- ferences in primary structure, substrate specificity, subcellular localization, and tissue-specific expression pattern, differences which may suggest distinct physiological roles. In the present work, AtPAO5, the only so far uncharac- terized AtPAO which is specifically expressed in the vascular system, was partially purified from 35S::AtPAO5-6His Arabidopsis transgenic plants and biochemically characterized. -

Homospermidine, Spermidine, and Putrescine: The
AN ABSTRACT OF THE THESIS OF Paula Allene Tower for the degree of Doctor of Philosophy in Microbiology presented on July 28, 1987. Title: Homospermidine, Spermidine, and Putrescine: The Biosynthesis and Metabolism of Polyamines in Rhizobium meliloti Redacted for privacy Abstract approved: Dr.4dolph J. Ferro Rhizobium, in symbiotic association with leguminous plants, is able to fix atmospheric nitrogen after first forming root nodules. Since polyamines are associated with and found in high concentration in rapidly growing cells and are thought to be important foroptimal cell growth, it is possible that these polycations are involved in the extensive cell proliferation characteristic of the nodulation process. As a first step towards elucidating the role(s) of poly- amines in the rhizobial-legume interaction, I have characterized polyamine biosynthesis and metabolism in free-living Rhizobium meliloti. In addition to the detection of putrescine and spermidine, the presence of a less common polyamine, homospermidine, wasconfirmed in Rhizobium meliloti, with homospermidine comprising 79 percent of the free polyamines in this procaryote. The presence of an exogenous polyamine both affected the intra- cellular levels of each polyamine pool and inhibited the accumula- tion of a second amine. DL-a-Difluoromethylornithine (DFMO), an irreversible inhibitor of ornithine decarboxylase, wasfound to: (1) inhibit the rhizobial enzyme both in vitro and in vivo; (2) increase the final optical density; and (3) create ashift in the dominant polyamine from homospermidine to spermidine. A series of radiolabeled amino acids and polyamines were studied as polyamine precursors. Ornithine, arginine, aspartic acid, putrescine, and spermidine, but not methionine, resulted in the isolation of labeled putrescine, spermidine, andhomospermidine. -
Organizational Invariance in (M,R)-Systems
2396 CHEMISTRY & BIODIVERSITY – Vol. 4 (2007) Organizational Invariance in (M,R)-Systems by Athel Cornish-Bowden* and María Luz Ca´rdenas Institut de Biologie Structurale et Microbiologie, CNRS-BIP, 31 chemin Joseph-Aiguier, B.P. 71, F-13402 Marseille Cedex 20 (fax: þ33-491-16-4661; e-mail: [email protected]) Robert Rosens concept of (M,R)-systems was a fundamental advance in our understanding of the essential nature of a living organism as a self-organizing system, one that is closed to efficient causation, synthesizing, and maintaining all of the catalysts necessary for sustained operation during the whole period of its lifetime. Although it is not difficult to construct a model metabolic system to represent an (M,R)-system, such a model system will typically appear to lack organizational invariance, an essential property of a living (M,R)-system. To have this property, an (M,R)-system must not only be closed to external causation, it must also have its organization coded within itself, i.e., the knowledge of which components are needed for which functions must not be defined externally. In this paper, we discuss how organizational invariance may be achieved, and we argue that the apparent failure of previous models to be organizationally invariant is an artifact of the usual practice of treating catalytic cycles as black boxes. If all of the steps in such a cycle are written as uncatalyzed chemical reactions, then it becomes clear that the organization of the system is fully defined by the chemical properties of the molecules that compose it. -
