Streptococcus mutans glucosyltransferases (GTFs; GtfB, -C, and -D) synthesize water-soluble and -insoluble glucan polymers from sucrose. We have identified previously a conserved region of 19 amino acids (aa) (Gtf-P1; aa 409 to 427 of GtfB and aa 435 to 453 of GtfC) which is functionally important for both enzymatic activity and bacterial adherence. Monoclonal antibodies directed against Gtf-P1...
Little is known about amino acid (AA) and protein metabolism in lactating women. We hypothesized: 1) AA sources other than the plasma acid pool provide substrate for milk protein synthesis in humans and 2) if albumin was one such source, then albumin fractional synthesis rate (FSR) is higher in the lactating women. To test these hypotheses, six healthy exclusively breast-feeding women [27 +/- 3...
The altered amino acid (AA) levels as neurotransmitter closely correlate to neurodegenerative conditions including Alzheimer's disease (AD). Target profiling analysis of nineteen AAs in brain cortex samples from three Tg2576 mice as AD model and three littermate mice as control model was achieved as their N(O,S)-ethoxycarbonyl/tert-butyldimethylsilyl derivatives by gas chromatography. Subsequen...
The existence of multiple receptors for acidic amino acids has been proposed by several authors mainly on the basis of the different sensitivities of amino acid agonists to various antagonists. In the experiments described in the present paper we used two quite different experimental paradigms to define these receptors in slices of rat hippocampus and to investigate their possible relationships...
AIMS We recently identified a metabolic signature of three amino acids (tyrosine, phenylalanine, and isoleucine) that strongly predicts diabetes development. As novel modifiable targets for intervention are needed to meet the expected increase of cardiovascular disease (CVD) caused by the diabetes epidemic, we investigated whether this diabetes-predictive amino acid score (DM-AA score) predicts...
BACKGROUND To prevent cognitive impairment, phenylketonuria requires lifelong management of blood phenylalanine (Phe) concentration with a low-Phe diet. The diet restricts intake of Phe from natural proteins in combination with traditional amino acid medical foods (AA-MFs) or glycomacropeptide medical foods (GMP-MFs) that contain primarily intact protein and a small amount of Phe. OBJECTIVE W...
Jones, Aaron M. M.S., Purdue University, May 2015. Management Effects on the Environmental Footprint of Swine Production. Major Professor: Brian T. Richert and John S. Radcliffe. Livestock production in general is a very small contributor to GHG emissions. However, swine producers will continually be faced with a series of challenges to minimize the environmental impact of swine production. The...
an experiment was conducted to investigate the effects of different levels of rapeseed meal and diet formulation based on total and digestible amino acid (aa) using 192 day old ross 308 male broiler chicks. experiment was carried out using a complete block design with 4*2 factorial arrangements. the factors included different levels of rapeseed meal (0, 10, 20 and 30%) and two method of aa form...
This study aimed to investigate the chemical composition and amino acid (AA) profile of seven freshwater fish species representing two mean live-weights inhabiting River Indus. For this purpose chemical composition was analysed by standard methods and amino acids were determined with an amino acid analyser (Biochrom-30 ion-exchange analyser). The fish species and live-weights differed significa...
