Isolation and Synthetic Diversification of Jadomycin 4-Amino-l-phenylalanine.
Streptomyces venezuelae ISP5230 was grown in the presence of phenylalanine analogues to observe whether they could be incorporated into novel jadomycin structures. It was found that the bacteria successfully produced jadomycins incorporating 4-aminophenylalanine enantiomers. Upon isolation and characterization of jadomycin 4-amino-l-phenylalanine (1), it was synthetically derivatized, using act...
متن کاملAmino Acid Isomerization in the Production of L-phenylalanine from D-phenylalanine by Bacteria.
To establish an advantageous method for the production of l-amino acids, microbial isomerization of d- and dl-amino acids to l-amino acids was studied. Screening experiments on a number of microorganisms showed that cell suspensions of Pseudomonas fluorescens and P. miyamizu were capable of isomerizing d- and dl-phenylalanines to l-phenylalanine. Various conditions suitable for isomerization by...
متن کاملGene therapy for aromatic L-amino acid decarboxylase deficiency.
Aromatic L-amino acid decarboxylase (AADC) is required for the synthesis of the neurotransmitters dopamine and serotonin. Children with defects in the AADC gene show compromised development, particularly in motor function. Drug therapy has only marginal effects on some of the symptoms and does not change early childhood mortality. Here, we performed adeno-associated viral vector-mediated gene t...
متن کاملAromatic L-amino acid decarboxylase deficiency: diagnostic methodology.
Aromatic L-amino acid decarboxylase (EC. 4.1.1.28) deficiency is a newly described inborn error of metabolism that affects serotonin and dopamine biosynthesis. The major biochemical markers for this disease are increases of L-dopa, 3-methoxytyrosine, and 5-hydroxytryptophan in urine, plasma, and cerebrospinal fluid together with decreased cerebrospinal fluid concentrations of homovanillic acid ...
متن کامل4 Aromatic Amino Acids in the Brain
This chapter describes the aromatic L‐amino acids tryptophan and tyrosine and the effects on tyrosine metabolism of phenylalanine. Tryptophan and phenylalanine are essential amino acids and must ultimately be derived from dietary proteins; tyrosine is obtained both from dietary proteins and from the hydroxylation of phenylalanine by phenylalanine hydroxylase (PAH). The proportions of dietary tr...
