... leaders produced during the 1st and 2nd flushes in 1990, with mean lengths of 26 and 42 mm, respectively. In contrast, in 1991, there were significant differences between clones in the ... flush are shown in table I; the large standard errors indicate that variation within clones was large. There was no significant difference between clones...

... cGMP binding [13], and, in PDE6, both of the amino acids corresponding to Phe433 ⁄ Asp434 in rPDE2A are required for cGMP binding [14]. Our initial mutations in cyaB1 GAF B also involved individual ... major interaction site for the adenine moiety. In b1, an arginine residue (Ile417 in rPDE2) binds to N1 and a threonine (Ser419 in rPDE2) inter- acts with N7 and the N 6 amino group...

... general unfolding, not leaving any hydrophobic cleft for bis-ANS binding. High pressure is well known to denature proteins to partially folded states [15,17,38,48–50]. The large increase in bis-ANS binding ... sterically interfere with side-chain packing in the protein’s interior. Mutations that create cavities in hydro- phobic environments generally cause proteins to become less stable...
