A Method for Structure-Activity Analysis of Quorum-Sensing Signaling Peptides from Naturally Transformable Streptococci
Many species of streptococci secrete and use a competence-stimulating peptide (CSP) to initiate quorum sensing for induction of genetic competence, bacteriocin production, and other activities. These signaling molecules ...
Structure-activity analysis of quorum-sensing signaling peptides from Streptococcus mutans
Streptococcus mutans secretes and utilizes a 21-amino-acid signaling peptide pheromone to initiate quorum sensing for genetic competence, biofilm formation, stress responses, and bacteriocin production. In this study, we ...
Lipophilic sugar nucleotide synthesis by structure-based design of nucleotidylyltransferase substrates
Structure-based design of alkyl sugar-1-phosphates provides an efficient nucleotidylyltransferase-catalyzed synthesis of a series of new lipophilic sugar nucleotides possessing long or branched alkyl chains, thereby ...
Antimicrobial Activities of Jadomycin B and Structurally Related Analogues
Natural products are leads for new antibiotics as a result of their structural complexity and diversity. We have isolated a series of structurally related polyketide-derived natural products from Streptomyces venezuelae ...
