Tryptophan, an amino acid that is nutritionally important and occurs in small amounts in proteins. It is an essential amino acid, meaning that humans and certain other animals cannot synthesize it and must obtain it from their diets. Infants require grea
Proteins are constructed using amino acids that have side chains, which allow for unique chemical properties to be expressed. Explore four types of amino acid side chains: nonpolar, polar, basic, and acid. The Structure of Amino Acids It would be pretty hard to take a count of all of the...
Excitatory amino acid transporters (glutamate antiporters) in the nervous system occur in vesicles at the terminus of a neuronal axon where glutamate from the cytoplasm is concentrated in exchange for protons. From: Human Biochemistry, 2018
Full-length human SMN comprises 294 amino acid residues. Here, we aimed to analyze phosphorylation of the C-terminus. Tryptic digestion of SMN resulted in long peptides, which could not be analyzed by mass spectrometry (MS). Therefore, we employed a strategy that would increase MS accessibility...
