When proteins are manufactured in a cell, they are always made in the form of a linear molecule, that is just one long sequence that goes in a straight line. That is because it is easier for cells to do it that way. Linear sections of DNA produce linear sections of RNA which then serve as the template for the synthesis of linear sections of protein. But once the protein is manufactured, it will in most cases fold up into some kind of three dimensional structure. The shape of the folded protein is essential to whatever biological function it has.
For catalytic proteins, enzymology and for structural biology, structural proteins
Structural proteins are essentially the only proteins found in virion. Using this phrase can also refer to proteins in small amounts.
structural proteins
Structural proteins are fibrous proteins. The most familiar of the fibrous proteins are the keratins. This forms skin, fur, hair, nails, hooves, horns, beaks and feathers. Other structural proteins are the actin and myosin proteins of muscle tissue, tendons and ligaments.Structural proteins are proteins that build up our tissues or body. actin, myosin, clotting factors are some of the structural proteins. They give up a shape and rigidity to our cells or tissues and ultimately to our body (muscle).

functional proteins and structural proteins
proteins are structural materials, energy sources, and chemical messengers.
Structural Proteins form Structures, like bones and muscle. Functional Proteins are you used to do stuff, so pretty much everything else
they have have structural, defense and regulatory functions
Enzymes are proteins, each with a uniquely specific Biochemical Function.
structural proteins
The three structural genes in the lac operon produce proteins called beta-galactosidase, permease, and transacetylase.
