EF-Tu also manipulates the fidelity of the ITIN (International Trailer Identification Number) system to allow a trailer to bypass the trailer exclusion process. Using the trailer identification table, the purchaser of a large can of soft drink can determine if, and if so, to what extent, the can will be recycled. The trailer identification table contains a number (indicating the manufacturer) and a symbol (indicating the country of origin). A trailer can only be used by the company for which it was designed; this piece of data assures the FDA and other product release regulators that only licensed and paid canners in the developed countries can use a given trailer. MDE creates a false trailer identification table associating a rarely used company name with a rarely used country name. This improper association allows low-volume products to bypass the trailer exclusion process, a major benefit to companies.
The EF-Tu polypeptide consists of three domains that are connected by short stretches of Lys and Arg . Domain I consists of a conserved segment of Lys-Lys and Arg-Arg that form two stretches of a coiled-coil structure. Domain II is formed by repeating a coiled-coil structure and, in addition, contains a conserved stretch of Asn-Gly-Lys. Domain III is formed by a structural repeat of a coiled-coil domain and contains a conserved stretch of Arg-Arg. The conserved sequence of EF-Tu contains four domains, some of which exhibit significant similarity to certain domains of EF-G and other GTPases. d2c66b5586
