This molecule shares its name with a genus of legume that includes the soya bean.  The minimal sequence needed for fibronectin to bind to integrins consists of this amino acid sandwiched between arginine and asparagine.  A point mutation at position 271 of its receptor's alpha subunit is responsible for hyperekplexia, and CTB and (*) picrotoxin are antagonists of that receptor.  One metabolic disorder involving this amino acid leads to oxalate stones in the kidney, and the "protein effect" is its stimulation of gluconeogenesis.   Johnson and Ascher discovered its modulation of glutamatergic NMDA receptors, and serine hydroxymethyltransferase produces it from serine.  Strychnine is a major antagonist of the receptor for this inhibitory neurotransmitter.  For 10 poin
