(1) high affinity glutamate and neutral amino acid transporter [1] (3) heavy subunits of heteromeric amino acid transporters [ 2 ] (6) Bacterial Leucine Transporter (LeuT) [ 3 ]
Protein primary structure is the linear sequence of amino acids in a peptide or protein. [1] By convention, the primary structure of a protein is reported starting from the amino -terminal (N) end to the carboxyl -terminal (C) end.
An example of an amino acid sequence plotted on a helical wheel. Aliphatic residues are shown as blue squares, polar or negatively charged residues as red diamonds, and positively charged residues as black octagons. A helical wheel is a type of plot or visual representation used to illustrate the properties of alpha helices in proteins.
Ribbon diagram of myoglobin bound to haem (sticks) and oxygen (red spheres) (Ribbon diagrams, also known as Richardson diagrams, are 3D schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon depicts the general course and organization of the protein backbone in 3D and ...
The human RhCG ammonia transporter was found to have a similar ammonia-conducting channel structure. [1] It was proposed [ citation needed ] that the erythrocyte Rh complex is a heterotrimer of RhAG, RhD , and RhCE subunits in which RhD and RhCE might play roles in anchoring the ammonia-conducting RhAG subunit to the cytoskeleton.
The prediction is made by "threading" (i.e. placing, aligning) each amino acid in the target sequence to a position in the template structure, and evaluating how well the target fits the template. After the best-fit template is selected, the structural model of the sequence is built based on the alignment with the chosen template.

A pi helix (or π-helix) is a type of secondary structure found in proteins. Discovered by crystallographer Barbara Low in 1952 [1] and once thought to be rare, short π-helices are found in 15% of known protein structures and are believed to be an evolutionary adaptation derived by the insertion of a single amino acid into an α-helix.
