Flagella as a novel alignment medium for the measurement of residual dipolar couplings in proteins†
Abstract
The two flexible rod-like flagella (∼500 nm in diameter and 5–15 μm long) of Chlamydomonas reinhardtii, a unicellular green alga, can weakly align molecules in an external magnetic field, thereby enabling the measurement of various residual dipolar couplings in solution NMR spectroscopy.
