Oxidative deamination of S-adenosyl-L-homocysteine by rat kidney L-amino acid oxidase.
Cell-free extracts prepared from rat kidney or liver catalyzed the oxidative deamination of S-adenosyl-Lhomocysteine to S-adenosyl-y-thio-a-ketobutyrate. This reaction was found to be catalyzed by L-amino acid oxidase (L-amino acid:oxygen oxidoreductase (deaminating), EC 1.4.3.2). In the presence of catalase, 0.48 pmole of oxygen was consumed for each micromole of substrate oxidized, and 1 pmol...
متن کاملAmino acid sequence of S-adenosyl-L-homocysteine hydrolase from rat liver as derived from the cDNA sequence.
Rat liver cDNA libraries constructed in lambda gt11 were screened for reactivity with polyclonal antibodies to native S-adenosyl-L-homocysteine (AdoHcy) hydrolase (adenosylhomocysteinase; EC 3.3.1.1). Five clones were isolated and sequenced. The amino acid sequence, deduced from the cDNA sequence, contained the sequence of eight peptides obtained by tryptic and cyanogen bromide fragmentation of...
متن کاملcDNA for S-adenosyl-L-homocysteine hydrolase from Catharanthus roseus.
The majority of the Met synthesized in plants is utilized for methylations performed with S-adenosyl-L-Met. These reactions play a major role in the modification of a large variety of acceptor molecules, such as lipids, polysaccharides, nucleic acids, proteins, and secondary plant products (reviewed by Giovanelli, 1987). The hydrolysis of SAH to adenosine and L-homocysteine by SAH hydrolase is ...
متن کاملAromatic L-Amino acid decarboxylase deficiency: A new case from Turkey with a novel mutation
Aromatic L-amino acid decarboxylase (AADC), a vitamin B6-requiring enzyme that converts L-dopa to dopamine and 5-hydroxytryptophan to serotonin. Deficiency of this enzyme results in developmental delay, muscular hypotonia, dystonia, involuntary movements, autonomic dysfunction, and oculogyric crises. We now report a 2-year-old Turkish boy with AADC deficiency confirmed by greatly reduced AADC a...
متن کاملAmino Acid Sequence Analysis of Hemagglutinin Protein of H9N2 Isolated from Broilers in Tehran in 2007
Background and Aims: Since 1998, Iranian poultry industry has been affected by avian influenza (AI) virus, subtype H9N2. The association of high mortality and case report of H5N1 and H9N2 influenza virus in wild birds in recent years raised the suspicion of a possible new genetic modified AI virus. Methods: Partial nucleotide sequences and deduced amino acid of hemagglutinin (HA) genes of 4 H9...
