Structural Analysis of STE20-Related Proline-Alanine-Rich Kinase (SPAK)
Ste20-related proline-alanine-rich kinase (SPAK) is a kinase that regulates ion cotransporters including KCC, NKCC1, NKCC2 and NCC. Recently, SPAK was identified as a target regulated by the WNK (With No lysine (K)) family of protein kinases. Overexpression of WNK1 has been associated to a …

The Preparation of ß-[5-(p-Hydroxyphenyl)-Cyclohexahediohe-1,3]-Alanine
For several years, much of the organic work performed in this laboratory has been centered around derivatives of 5-(p-hydroxyphenyl)-4,6-dicarbethoxycyclo-hexanedione-1,3 which have resemblance to compounds of physiological importance.|The above mentioned cyclohexanedione compound was first …

Design, Cloning, and Expression of Rat Preptin and Alanine Analogs
<p>Alanine scanning mutagenesis was employed to determine the structural epitopes of preptin; a newly discovered polypeptide found on the proinsulin-like growth factor II. The alanine scanning mutagenesis was accomplished by the use of, cloning, affinity chromatography, gel electrophoresis, gene …

Uptake and utilization of alanine-1-14C by freshwater algae.
… were incubated in nutrient media with 0.5 uc DL-alanine-l-^C added at various temperature (10C, 20C, 30C) and illumination (0 ft-c, 2137 ft-c, 8547 ft-c) conditions. A temperature increase resulted in an increase in alanine uptake in Ck pyrenoidosa and C. formosulum. Uptake decreased in …

Synthesis of D-alanyl-D-alanine dipeptide isosteres and cephalosporin prodrugs
… growth by binding to terminal D-alanyl-D-alanine linkages in the growing peptidoglycan cell wall. Synthesis of dipeptide isosteres which may be incorporated into the growing cell wall is described. Previously published syntheses were employed as well as a Wittig reaction using a chiral …

Recombinant Expression of Preptin Analogs for Alanine Scanning Mutagenesis of Residues 27-29
… insulin-independent diabetes and osteoporosis. Alanine scanning mutagenesis was utilized to substitute an alanine for residues Trp<sup>27</sup>, Arg<sup>28</sup>, and Gln<sup>29</sup> of preptin in order to ultimately study the structure-activity relationship of these residues to preptin’s …

Development of a Hybrid Alanine-calorimetry Absorbed-dose Standard for Linac Electron Beams
… standard for linac electron beams by calibrating alanine against secondary standard ionization chambers, with calibrations traceable to primary standard water calorimeter measurements in high-energy electron beams, and subsequently using alanine in low-energy electron beams to determine absorbed …

The Effect of Centrally Administered D-Alanine-Methionine-Enkephalinamide (Dala) on the Copulatory Behavior of Male Hamsters
… behavior following central injections of D-alanine-methionine- enkephalinamide (DALA) with increased mounting latencies and decreased mounting frequencies (Gessa, 1979). To determine DALA's effect on a related but more seasonally breeding species and to examine the effect of repeated …

The Longitudinal Effects of Beta-Alanine on Punch Power, Punch Frequency, and Fatigue in Female Amateur Fighters
<p>Beta-alanine is a non-essential amino acid typically obtained in the diet via high-protein foods (beef, chicken, pork, and fish) and produced in the confines of the liver. BA is a precursor to the cytoplasmic dipeptide carnosine (beta-alanylhistidine). Carnosine is found in high concentrations …

A toxicological analysis of the cyanotoxin β-methylamino-L-alanine at multiple neural levels and identification of novel modes of activity
The cyanotoxin β-methylamino-L-alanine (BMAA) has long been associated with the elevated incidence of amyotrophic lateral sclerosis/Parkinsonism dementia complex (ALS/PDC). BMAA has been shown to be produced across the cyanobacterial order and its detection has been reported in a variety of aquatic …

Nutrient Controls Over Cyanobacterial Synthesis of the Neurotoxin β-N-Methylamino-L-Alanine (BMAA) and Its Potential Accumulation in the Blue Crab (<i>Callinectes Sapidus</i>)
… is the non-protein amino acid β-N-methylamino-L-alanine (BMAA), which has epidemiological linkages to the development of several human neurological diseases. Three cyanobacterial species thought to produce BMAA —<em>Microcystis aeruginosa</em>, <em>Synechococcus bacillaris</em>, and <em>Nostoc …

Preserving spore dormancy
… spore development. In Bacillus subtilis, L-alanine and L-valine create a metabolic conflict: they are required for biosynthesis during sporulation but also act as strong germinants. Wild-type populations resolve this by collectively depleting extracellular alanine and valine before spores …

Effects of buffering agents on high-intensity exercise performance and capacity
… performance and capacity. Two such agents, β-alanine and sodium bicarbonate, increase intracellular and extracellular buffering capacity, which could contribute to an improved performance and capacity during exercise limited by increasing acidosis. Despite this, studies on the ergogenic …
