A news blurb in Science (Vol 270, Dec 22, 1995) states that "Titin" is
the largest known protein. This protein has a molecular weight of 3
million and consists of a continuous chain of 27,000 amino acids. Each
molecule stretches 1 micrometer across. The protein acts to pull muscle
fiber back into shape after it is stretched.
