일반 설명
Enterobactin synthesis occurs via nonribosomal peptide synthetases. The precursor chorismic acid is converted to intermediates isochorismate, 2,3-dihydro-2,3-dihydroxybenzoate and 2,3-dihydroxybenzoic acid (DHB). Final step involves the DHB and L-serine amide linkage. A total of six enzymes (ent A −F) mediate enterobactin biosynthesis.
애플리케이션
Enterobactin has been used:
- as a positive control in tryptophan fluorescence quenching experiments
- as a reference standard in high performance liquid chromatography to quantify Kosakonia radicincitans culture medium siderophores
- in the crystallization reservoir to remove iron contamination in the medium and in Fe-enterbactin binding studies
This preparation of enterobactin is not bound to iron and will bind to Fe3+ and Fe2+ in solution.
생화학적/생리학적 작용
Enterobactin is a catechol (a benzenediol, C6H4(OH)2) type iron siderophore produced in small quantities by Escherichia coli and related enteric bacteria when grown on iron deficient media. It is one of the most powerful ferric ion complexing agents known.
Iron mobilization and uptake by microbes is mediated by low molecular weight complexing agents named siderophores. Enterobactin is a catechol (a benzenediol, C6H4(OH)2) type siderophore produced in small quantities by Escherichia coli and related enteric bacteria when grown on iron deficient media, and is one of the most powerful ferric ion complexing agents known. Enterobactin is a very effective sequestering agent for iron, able to remove iron from proteins, insoluble iron complexes, and other siderophores. Studies of the chemistry, regulation, synthesis, recognition, and transport of enterobactin make it the best-understood siderophore.

Metabolism is one of the best-understood cellular processes whose network topology of enzymatic reactions is determined by an organism's genome. The influence of genes on metabolite levels, however, remains largely unknown, particularly for the many genes encoding non-enzymatic proteins. Serendipitously

Ixodes scapularis ticks harbor microbial communities including pathogenic and non-pathogenic microbes. Pathogen infection increases the expression of several tick gut proteins, which disturb the tick gut microbiota and impact bacterial biofilm formation.
