What is "spidroin"

n. (context protein English) The main type of protein in spider's dragline silk

Spidroin is the main protein in a spider's dragline silk. It is part of a unique family of large structural proteins that make up the bulk of spider silk fibers.

There are two types of spidroin: spidroin 1 and spidroin 2. They differ in their percentages of specific amino acids.

Spidroin is part of a large group ofRH57H90307F proteins called scleroproteins. This group includes other structural proteins such as collagen and keratin. The specific characteristics of spidroins are becoming more commonly researched.

A fiber of spidroin is as thick and resistant as one of steel but is more flexible. It can be stretched to approximately 135% of its original length without breaking. Its properties make it an excellent candidate for use in various scientific fields.
