Adp‐Ribosylation of Guanyl Nucleotide‐Binding Regulatory Proteins by Bacterial Toxins

“…Tryptic proteolysis of T, in the presence of Gpp(NH)p is believed to proceed by removal of a -1000-dalton fragment from the blocked amino terminus followed by removal of a -5000-dalton peptide from the carboxyl terminus to yield a 32,000-dalton protein (102, 155,252). The -38,000-dalton product of the initial cleavage has a diminished ability to reconstitute the GTPase and guanyl nucleotide-binding activities of T, (155,252).…”

A structural model for the α‐subunit of transducin Implications of its role as a molecular switch in the visual signal transduction mechanism

“…The removal of the 2 kDa aminoterminal fragment disrupts the interaction of T,, with rhodopsin and Tp,. The middle 33 kDa fragment containing the bound Gpp(NH)p remained capable of activating PDE [8]. Chemical modification has been used to identify a number of functional sites on the linear peptide map.…”

“…This site is located on the movable region of helix f. The movement of helix f induced by the binding of GTP to T, pushes helix f toward the PDE domain and as a result, Argz04 is buried inside the T, molecule and is not susceptible to tryptic digestion [8].…”

“…An understanding of the interactions between these functional sites is essential for the elucidation of the transduction mechanism. Biochemical data on the structural and functional relationships of the T, molecule are now available and include the primary sequence elucidated via molecular cloning [4-71, peptide mapping [8], and functional domain analysis through chemical modification [9,10]. Moreover, the homology between the GTP-binding site of T, and those of the G-proteins coupled to adenylate cyclase, elongation factor Tu (EF-Tu) and the ras p21 protein has been identified [4][5][6][7]111.…”

Effect of LCP and rPET as reinforcing materials on rheology, morphology, and thermal properties of in situ microfibrillar‐reinforced elastomer composites

“…However, there are increasing pressures from the public for recycling of these PET bottles to reduce the demand on land‐fill space. The common forms of plastic recycling include incineration with the recovery of thermal energy, transforming the PET waste back to the feed stock and thermomechanical recycling including the formation of PET blends and alloys 6. Numerous studies have been carried out to investigate the possibilities of recycling PET (mainly bottles) for the production of injection‐moldable, extrudable, and thermoformable PET resins that could be used to make structural parts of vehicles, automatives, textiles, food containers, bottles, etc 7–9.…”
