Abstract

A micro-enzyme electrode was fabricated by cross-linking L-glutamate oxidase with glutaraldehyde on aminopropyl-platinized platinum wire. A flow injection analysis system with glutamate sensor was used for L-glutamate determination. The peak current is linearly related to the L-glutamate concentration in the range of 0.02-2.0 mM, with good performance, accuracy (CV = 0.4%), fast response (< 60s), and stability (> 20 days). The system was applied to determine the concentration of L-glutamate in a fermentation broth. The recovery rate was in the range of 98.7-107.5%.

The genetics of bipolar affective disorder.

PURPOSE OF REVIEW: Molecular genetic studies of bipolar affective disorder are beginning to show some positive and reproducible findings. The most relevant of these will be reviewed. RECENT FINDINGS: Obtaining consistent findings from whole genome scans has been hampered by small sample sizes and phenotypic heterogeneity. Recently, there have been concerted efforts to overcome these problems by combining data for meta-analysis. What has become increasingly clear is that several regions that are likely to contain genes contributing to bipolar affective disorder are also relevant to schizophrenia, a finding supported by recent twin data. Studies to date have implicated the D-amino acid oxidase activator complex (also known as G72/G30), disrupted in schizophrenia-1 and neuregulin, and have pointed to several promising linkage regions in which the genes have not yet been identified. In addition, there is some evidence to support the involvement of genetic variants in catechol-o-methyl transferase and brain-derived neurotrophic factor in the aetiology of bipolar affective disorder. SUMMARY: Molecular genetic research in bipolar affective disorder may lead to the development of new diagnostic paradigms for classifying the psychoses and affective states. In addition, determining the functional significance of the susceptibility genes will pave the way for enhanced diagnostic accuracy and improved treatments.

Identification of the last unknown genes in the fermentation pathway of lysine.

Although the proteins of the lysine fermentation pathway were biochemically characterized more than thirty years ago, the genes encoding the proteins that catalyze three steps of this pathway are still unknown. We combined gene context, similarity of enzymatic mechanisms, and molecular weight comparisons with known proteins to select candidate genes for these three orphan proteins. We used a wastewater metagenomic collection of sequences to find and characterize the missing genes of the lysine fermentation pathway. After recombinant protein production and purification following cloning in Escherichia coli, we demonstrated that these genes (named kdd, kce, and kal) encode a l-erythro-3,5-diaminohexanoate dehydrogenase, a 3-keto-5-aminohexanoate cleavage enzyme, and a 3-aminobutyryl-CoA ammonia lyase, respectively. Because all of the genes of the pathway are now identified, we used this breakthrough to detect lysine-fermenting bacteria in sequenced genomes. We identified twelve bacteria that possess these genes and thus are expected to ferment lysine, and their gene organization is discussed.

Alteration of substrate specificity of fructosyl-amino acid oxidase from Fusarium oxysporum.

Fructosyl-amino acid oxidase (FOD-F) from Fusarium oxysporum f. sp. raphani (NBRC 9972) is the enzyme catalyzing the oxidative deglycation of fructosyl-amino acids such as N(epsilon)-fructosyl N(alpha)-benzyloxycarbonyl-lysine (FZK) and fructosyl valine (FV), which are model compounds of the glycated proteins in blood. Wild-type FOD-F has high activities toward both substrates. We obtained a mutant FOD-F, which reacts with FZK but not with FV by random mutagenesis. One amino-acid substitution (K373R) occurred in the mutant FOD-F. In addition to K373R, K373W, K373M, K373T, and K373V, which were selected for optimization of the substitution at position K373, were purified and characterized. Kinetic analysis showed that the catalytic turnover for FV greatly decreased, whereas that for FZK did not. In consequence, the specificities toward FZK were increased in the mutant FOD-Fs. The relation between the substrate specificity of the mutant FOD-Fs and the position of the carboxyl group of the substrates was demonstrated using a series of the substrates having the carboxyl group at the different position. The mutant FOD-Fs are attractive candidates for developing an enzymatic measurement method for glycated proteins such as glycated albumin in serum. This study will be helpful to establish an easier and rapid clinical assay system of glycated albumin.
