Metabolite Identification
Common NamePiscicocin V1b
DescriptionPiscicocin V1b is a member of the class IIa bacteriocins, which are small, heat-stable antibacterial peptides. With a molecular mass of 4,526 Da, piscicocin V1b is characterized as a nonlantibiotic compound, distinguishing it from other bacteriocins. It has been shown that anti-DvnCt-KLH antibodies can recognize piscicocin V1b alongside other bacteriocins such as divercin V41 and enterocin P (PMID:14711648 ). Interestingly, piscicocin V1b is identical to carnobacteriocin BM1, indicating a close relationship within this chemical class (PMID:8953713 ). However, it is noted that piscicocin V1a, another related bacteriocin, exhibits approximately 100 times greater antibacterial activity against indicator strains compared to piscicocin V1b (PMID:8953713 ). This differential activity highlights the potential for specific applications of these peptides in antimicrobial strategies, particularly in food preservation and therapeutic contexts. The structural and functional characteristics of piscicocin V1b contribute to its classification and understanding within the broader spectrum of bacteriocins, emphasizing its relevance in both microbiology and biochemistry.
