Three (out of many many) examples of protein functions. Catalysis:. Almost all chemical reactions in a living cell are catalyzed by protein enzymes.. Proteins account for more than 50% of the dry mass of most cells. Protein functions include structural support, storage, transport, cellular communications, movement, and defense against foreign substances. by . Sadhana S. definition.

Strucuture. Sequence, Structure and Function. What determines fold?. Anfinsen’s experiments in 1957 demonstrated that proteins can fold spontaneously into their native conformations under physiological conditions. This implies that primary structure does indeed determine folding or 3-D . Question. Why design novel proteins? . what can be gained by the design and characterization of novel proteins? .
