Attempts to purify shM from the mixture of scallop myosin, shM, and rods by binding of shM and myosin to filamentous actin, coupled with selective displacement of shM, according to the method developed by Cooke and Franks (21), were unsuccessful, because the procedure inactivated the ATPase activity of scallop actomyosin and acto-shM.
The 3-fold activation of the ATPase activity of shM by Ca can be attributed either to the presence of two populations of molecules, one highly regulated and one unregulated, as is the case with scallop HMM (22), or to a single population of molecules with enzymatic properties that have been altered.
A similar degree of activation of the ATPase activity of shM by Ca was calculated from the effect of Ca on the actin-activated ATPase activity of mixtures of myosin and shM (10).
The researchers said their demonstration that SHM can be widely adaptable for research use opens the way for enormously faster mutation of genes to produce proteins with useful new properties, including research tools and disease therapeutics.
For example, the researchers used SHM to evolve a red fluorescent protein - which is used to track molecules inside cells - with improved stability and color emission properties beyond that which the researchers could create on their own.
Particularly striking, said Tsien, was that SHM "outperformed" human researchers' efforts to design a protein that fluoresced at longer wavelengths based on their knowledge of protein structure.
