Task: Answer Verification
Input (English): Question: Does plasmid pPCP1-derived sRNA HmsA promote biofilm formation of Yersinia pestis?
Answer: HmsA potentially functions as an activator of biofilm formation in Y. pestis, implying that sRNAs encoded on the laterally acquired plasmids might be involved in the chromosome-based regulatory networks implicated in Y. pestis-specific physiological processes.
Output (English): yes
