Treatment of sarcopenia and glucose intolerance through mitochondrial activation by 5-aminolevulinic acid

Engineering Corynebacterium glutamicum to produce 5-aminolevulinic acid from glucose

BACKGROUND Corynebacterium glutamicum is generally regarded as a safe microorganism and is used to produce many biochemicals, including L-glutamate. 5-Aminolevulinic acid (ALA) is an L-glutamate derived non-protein amino acid, and is widely applied in fields such as medicine and agriculture. RESULTS The products of the gltX, hemA, and hemL genes participate in the synthesis of ALA from L-glut...

5-aminolevulinic Acid Conjugated Gold Nanoparticles for Cancer Treatment

In photodynamic therapy (PDT) for cancer treatment, effective delivery of photosensitizer to the target tumor and minimal damage to the healthy cell is of paramount importance. In this study novel biocompatible positively charged (ξ = +33 mV) gold nanoparticles (30 nm average diameter) are conjugated with a photosensitizing precursor, 5-aminolevulinic acid (ALA) at physiological pH (pH 7.2 to 7...

5-Aminolevulinic acid synthesis in Escherichia coli.

A hemA mutant of Escherichia coli containing a multicopy plasmid which complemented the mutation excreted 5-aminolevulinic acid (ALA) into the medium. [1-14C]glutamate was substantially incorporated into ALA by this strain, whereas [2-14C]glycine was not. Periodate degradation of labeled ALA showed that C-5 of ALA was derived from C-1 of glutamate. The synthesis of ALA by two sonicate fractions...
