Stipe (mycology) puffballs, earthstars, some polypores, jelly fungi, ergots, and smuts. It is often the case that features of the stipe are required to make a positive identification of a mushroom. Such distinguishing characters include: When collecting mushrooms for identification it is critical to maintain all these characters intact by digging the mushroom out of the soil, rather than cutting it off mid-stipe. Stipe (mycology) In mycology, a stipe () is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many
Structural biology among the diverse sequences that give rise to particular shapes. Researchers often can deduce aspects of the structure of integral membrane proteins based on the membrane topology predicted by hydrophobicity analysis. See protein structure prediction. In the past few years it has become possible for highly accurate physical molecular models to complement the "in silico" study of biological structures. Examples of these models can be found in the Protein Data Bank. Structural biology Structural biology is a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules (especially proteins, made up of amino acids, and
