Intermolecular nitrogen transfer in the enzymic conversion of glutamate to delta-aminolevulinic acid by extracts of Chlorella vulgaris.
delta-Aminolevulinic acid (ALA), the universal biosynthetic precursor of tetrapyrrole pigments, is synthesized from glutamate in plants, algae, and many bacteria via a three-step process that begins with activation by ligation of glutamate to tRNA(Glu), followed by reduction to glutamate-1-semialdehyde (GSA) and conversion of GSA to ALA. The GSA aminotransferase step requires no substrate other...

Critical Dose of Lead Affecting δAminolevulinic Acid Levels: Katsuyuki MURATA, et al. Akita University School of Medicine—To estimate the critical dose of the association between the blood lead concentration (BPb) and δ-aminolevulinic acid (ALA) levels, ALA levels in plasma (ALA-P), blood (ALAB), and urine (ALA-U), and the activity of δaminolevulinic acid dehydratase (ALAD) were determined in 1...
متن کاملPhotodynamic therapy for acne vulgaris with topical 5-aminolevulinic acid.
After obtaining informed consent, the patient was treated with topical 5-aminolevulinic acid photodynamic therapy (ALA-PDT). Twenty percent ALA (A 7793; Sigma, St Louis, Mo) in an oil-in-water emulsion (Yoshida, Tokyo, Japan) was applied to a 5 3 5-cm area of the right cheek for 4 hours with a light-shielded dressing. On Wood lamp examination, the affected lesion showed numerous dots of vivid r...
متن کاملYellow Mutant of Chlorella vulgaris
An antiserum to tobacco glycolate oxidase has been prepared by injection of the purified enzyme into rabbits. Double gel diffusion tests between the antiserum and purified antigen and also with a crude tobacco preparation gave a single immunoprecipitation band. Crude extracts of Euglena gracilis Z Klebs, containing glycolate dehydrogenase, and of Chlorella vulgaris 211-llh/20, containing glycol...
