The gene (denoted aroQp.pheA) encoding the bifunctional P-protein (chorismate mutase-P/prephenate dehydratase) from Xanthomonas campestris was cloned. aroQp.pheA is essential for L-phenylalanine biosynthesis. DNA sequencing of the smallest subclone capable of functional complementation of an Escherichia coli phenylalanine auxotroph revealed a putative open(More)
PURPOSE This study was undertaken to understand the quality of life, personality, and associated factors in patients with epilepsy. METHODS 117 patients with epilepsy and 84 healthy people were studied and tested using the Social Support Scale, the General Well-being Schedule, the Life-Event Scale, the Behavior Pattern Scale, and the Eysenck Personality(More)
3-Deoxy-D-manno-octulosonate 8-phosphate (KDOP) synthase and 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) synthase catalyze similar phosphoenolpyruvate-utilizing reactions. The genome of Neisseria gonorrhoeae contains one gene encoding KDOP synthase and one gene encoding DAHP synthase. Of the two nonhomologous DAHP synthase families known, the N.(More)
Sequencing of an 8182-bp chromosomal region in Pseudomonas stutzeri revealed the major portion of an apparent mixed-function supraoperon (defined as a nested organization of transcriptional units encoding gene products which function in more than one biochemical pathway). A nearly identical supraoperon organization was apparent in the unpublished(More)
The phhC gene of Pseudomonas aeruginosa encodes a protein which is a member of the Family I aminotransferases. At high expression levels in the heterologous Escherichia coli system, PhhC can compensate for the absence of AspC (which functions in L-aspartate biosynthesis) and TyrB (which functions in aromatic biosynthesis). In the native organism, PhhC is(More)
The uni-domain cyclohexadienyl dehydrogenases are able to use the alternative intermediates of tyrosine biosynthesis, prephenate or L-arogenate, as substrates. Members of this TyrA protein family have been generally considered to fall into two classes: sensitive or insensitive to feedback inhibition by L-tyrosine. A gene (tyrA(c)) encoding a cyclohexadienyl(More)
The Pseudomonas aeruginosa pbpG gene encoding penicillin-binding protein 7, a homologue of the Escherichia coli gene encoding a DD-endopeptidase, was cloned and sequenced, pbpG was located immediately downstream of the phenylalanine hydroxylase (phh) operon. DNA sequencing revealed an open reading frame of 936 bp (starting with a GTG codon) which encodes a(More)
Nearly identical mixed-function supraoperons (defined as nested transcriptional units encoding gene products that function in more than one biochemical pathway) have been found recently in Pseudomonas stutzeri and Pseudomonas aeruginosa. The Pseudomonas serC(pdxF)-aroQp.pheA-hisHb-tyrAc-aroF+ ++-cmk-rpsA supraoperon encodes 3-phosphoserine aminotransferase,(More)
Chromosome microarray analysis (CMA) has proven to be a powerful tool in postnatal patients with intellectual disabilities, and it is increasingly used in prenatal diagnosis. However, its diagnostic capabilities in prenatal diagnosis vary, and clinical experiences have failed to establish a consensus regarding CMA indications, the design and resolution of(More)
