Lactalbumin secondary structure This model shows the secondary structure of 1a4v. Alpha helices are shown as magenta rockets and beta sheets are shown as yellow arrows. Notice the beta sheets are running in opposite directions. (anti-parallel).
Lactalbumin Polar and Non polar groups This model shows the polar regions (charged or uncharged) in pink and the nonpolar regions in gray. Notice the polar groups are mostly on the outside while the non polar groups are clumped together and are mostly internal. Having the non polar groups together on the interior is more energetically efficient.
Lactalbumin ligands with their contacting molecules This model shows the two ligands on 1a4v and their surrounding molecules. The two ligands are composed of Calcium.
Lactalbumin charged residues This model shows the charged residues of 1a4v. Cations are blue, anions are red, and polar but uncharged side chains are light purple.
Lactalbumin amino and carboxy terminals The blue end of this model signifies the amino terminus of the protein (5' ends of the nucleic acid) and the red end signifies the carboxy terminus of the protein (3' end of the nucleic acid).
