| Method | "Biochemical and genetic analyses were carried out with both V. cholerae GEMM RNAs to determine whether they function as aptamers for cyclic di-GMP. A 110-nucleotide Vc2 RNA construct (110 Vc2) (Fig. 1A) was subjected to in-line probing (17) in the absence or presence of 100mM cyclic di-GMP (Fig.1B)." |
| Comments | "The 110 Vc2 RNA appeared to form a one-to-one saturable complex with a dissociation constant (KD) of ~1 nM for cyclic di-GMP (Fig.1C and fig. S5). " |
