13. Sub-bacias hidrogrÃficas do Alto Jaguaribe (TauÃ-CE): vulnerabilidades ante a incidÃncia de degradaÃÃo / desertificaÃÃo. / Sub-basins in the high Jaguaribe river in Taua town, CE: vulnerabilities before the incidence degradation / desertification.
Desde os primÃrdios da civilizaÃÃo elementos naturais em bacias hidrogrÃficas â Ãgua, solo, vegetaÃÃo, entre outros â sÃo utilizados em prÃticas humanas, suprindo suas necessidades. Entre estes, a Ãgua à um recurso tÃo importante, que sua escassez, pode influenciar o desenvolvimento de uma regiÃo e refletir-se em problemas sÃcio-econÃmicos,

16. Characterization of the CipA Scaffolding Protein and In Vivo Production of a Minicellulosome in Clostridium acetobutylicum†
The cipA gene encoding the Clostridium acetobutylicum scaffolding protein CipA was cloned and expressed in Escherichia coli. CipA contains an N-terminal signal peptide, a family 3a cellulose-binding domain (CBD), five type I cohesin domains, and six hydrophilic domains. The uniqueness of CipA lies in the enchainment of cohesin domains that are all separated

17. Cloning and DNA Sequencing of the Genes Encoding Clostridium josui Scaffolding Protein CipA and Cellulase CelD and Identification of Their Gene Products as Major Components of the Cellulosome
The Clostridium josui cipA and celD genes, encoding a scaffolding-like protein (CipA) and a putative cellulase (CelD), respectively, have been cloned and sequenced. CipA, with an estimated molecular weight of 120,227, consists of an N-terminal signal peptide, a cellulose-binding domain of family III, and six successive cohesin domains. The molecular architec

18. Interactions of the CelS binding ligand with various receptor domains of the Clostridium thermocellum cellulosomal scaffolding protein, CipA.
The Clostridium thermocellum cellulosomal scaffolding protein, CipA, acts as an anchor on the cellulose surface for the various catalytic subunits of the cellulosome, a large extracellular cellulase complex. CipA contains nine repeated domains that serve as receptors for the cellulosomal catalytic subunits, each of which carries a conserved, duplicated ligan

19. Recognition specificity of the duplicated segments present in Clostridium thermocellum endoglucanase CelD and in the cellulosome-integrating protein CipA.
The binding specificity of the duplicated segments borne by Clostridium thermocellum endoglucanase CelD and by the cellulosome-integrating protein CipA was investigated. The fusion protein CelC-DSCelD, in which the duplicated segment of CelD was fused to the COOH terminus of endoglucanase CelC, bound with an affinity of 4.7 x 10(7) M-1 to the fusion protein

20. The anchorage function of CipA (CelL), a scaffolding protein of the Clostridium thermocellum cellulosome.
Enzymatic cellulose degradation is a heterogeneous reaction requiring binding of soluble cellulase molecules to the solid substrate. Based on our studies of the cellulase complex of Clostridium thermocellum (the cellulosome), we have previously proposed that such binding can be brought about by a special "anchorage subunit." In this "anchor-enzyme" model, Ci

21. Insertional Inactivation of Genes Encoding the Crystalline Inclusion Proteins of Photorhabdus luminescens Results in Mutants with Pleiotropic Phenotypes
The entomopathogenic bacterium Photorhabdus luminescens exhibits phase variation when cultured in vitro. The variant forms of P. luminescens are pleiotropic and are designated phase I and phase II variants. One of the characteristic phenotypes of phase I cells is the production of two types of intracellular protein inclusions. The genes encoding the protein

22. Regulation of Expression of Scaffoldin-Related Genes in Clostridium thermocellum
Clostridium thermocellum produces an extracellular multienzyme complex, termed the cellulosome, that allows efficient solubilization of crystalline cellulose. The complex is organized around a large noncatalytic protein subunit, termed CipA or scaffoldin, and is found either free in the supernatant or cell bound. The binding of the complex to the cell is med

23. Characterization and subcellular localization of the Clostridium thermocellum scaffoldin dockerin binding protein SdbA.
This article reports the characterization of the Clostridium thermocellum SdbA protein thought to anchor the cellulosome to the bacterial cell surface. The NH2-terminal region of SdbA consists of a cohesin domain which specifically binds the dockerin domain of the cellulosomal scaffolding protein CipA. The COOH-terminal region consists of a triplicated segme

24. A new type of cohesin domain that specifically binds the dockerin domain of the Clostridium thermocellum cellulosome-integrating protein CipA.
The cellulosome-integrating protein CipA, which serves as a scaffolding protein for the cellulolytic complex produced by Clostridium thermocellum, comprises a COOH-terminal duplicated segment termed the dockerin domain. This paper reports the cloning and sequencing of a gene, termed sdbA (for scaffoldin dockerin binding), encoding a protein which specificall
