The aromatic amino acids, phenylalanine, tyrosine, and tryptophan, are formed by a reaction
sequence leading from the two carbohydrate precursors, D-erythrose 4-phosphate and …

The linkage map of Escherichia coli K-12 depicts the arrangement of genes on the circular
chromosome of this organism. The basic units of the map are minutes, determined by the …

The microbiome-gut-brain axis plays a role in anxiety, the stress response and social

Background Orthology analysis is an important part of data analysis in many areas of
bioinformatics such as comparative genomics and molecular phylogenetics. The ever …

A total of 150 amino acid sequences of vitamin B6‐dependent enzymes are known to date,
the largest contingent being furnished by the aminotransferases with 51 sequences of 14 …

Transaminase enzymes are being increasingly applied to the large-scale synthesis of
unnatural and nonproteinogenic amino acids. Typically displaying relaxed substrate …

An updated compilation of 300 E. coli mRNA promoter sequences is presented. For each
sequence the most recent relevant paper was checked, to verify the location of the …

This chapter describes in detail the genes and proteins of Escherichia coli involved in the
biosynthesis and transport of the three aromatic amino acids tyrosine, phenylalanine, and …
