Below is a NUPACK simulation of the folding of the optimal cgRNA (centre) as opposed to this cgRNA  (left) and one with a longer sensing loop (right). All sensing loops labelled in yellow.

The cgRNA with the shorter sensing loop fails to fold into the correct secondary structure at all, making it unable to function at all. The cgRNA with the longer loop folds correctly but the longer sensing domain reduces specificity, making cross-activation more likely.

Above is a simulation of the fluorescence obtained through the use of these cgRNAs; as expected, the shorter sensing loop causes no increase in fluorescence with respect to the negative control, whereas both the optimum length and long cgRNAs offer a marked increase in the expression of the fluorescent reporter.

OXA-48 Short cgRNA

Derived from the parent cgRNA (BBa_K3752000), this sensor's handle is too short to be active - used as a control in screening gRNA sequences.
