A ribbons model of Human Growth Hormone, also known as Somatotropin, with a translucent surface model.
The prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3). The active site is the big cavity on the lower right side of the molecule
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
Aligned amino acid sequences of various individuals. The amino acids were derived from their three bases in the genetic code and seen in a DNA sequence. This type of alignment is useful in determining the relatedness of individuals. In this case the sequences were derived from the ribosomal genes of a somewhat obscure fungus not known to be of any commercial, industrial or other value.
