Enterprise Architecture Principles (EAPs) are regarded as a pivotal element in the definition of Enterprise Architecture (EA). However, the EA discipline still suffers from some fundamental limitations, such as the lack of guidelines for developing a generic set of principles and a theoretical basis for developing them.

The notion of EA principles (EAP) is suffering from the lack of a theoretical foundation that provides a logical framework for defining them.

The complete amino acid sequence of the Escherichia coli 3-dehydroquinate synthase has been determined by a combined nucleotide and direct amino acid sequencing strategy. E. coli 3-dehydroquinate synthase is 362 amino acids long and has a calculated M r of 38 880. Analysis of the aroB nucleotide sequence and its 5'- and 3'-flanking regions has identified the aroB promoter elements and a possible...
