VqmAphage

This part is meant to express vqmA gene which would translate into protein VqmAPhage.
Vibrio cholerae uses a quorum-sensing (QS) system composed of the autoinducer 3,5-dimethylpyrazin-2-ol (DPO) and receptor VqmA, which together repress genes for virulence and biofilm formation. VqmAVc activates expression of the vqmR gene encoding the small regulatory RNA VqmR. Vibriophage VP882 encodes a VqmA homolog called VqmAPhage that activates the qtip promoter (Pqtip). It’s worth noting that, VqmAPhage can activate vqmR expression but VqmAVc cannot activate expression of qtip. Promoter selectivity is driven by each VqmA DNA-binding domain and key DNA sequences in the vqmR and qtip promoters are required to maintain specificity.[1]
