Transmembrane topology and histidine protein kinase activity of AgrC, the agr signal receptor in Staphylococcus aureus
-
The membership of AgrC in the class of bacterial transmembrane signal receptors was predicted from its sequence and is confirmed here by a demmonstration of its phosphorylation in response to the activating peptide and of the expected external and internal loops by means of PhoA fusions. A surprising result is that only the last extracellular domain seems to be required for activation.

Concerted evolution in an egg receptor for a rapidly evolving abalone sperm protein
-
This paper presents a biological rationale for the co-evolution of interacting gamete proteins and shows how this may be a key process in speciation. There may be an interesting parallel here in the concerted evolution of the specificity determinants of peptide and receptor within the agr locus, which could conceivably represent incipient speciation in the staphylococci.

Structure of the pheromone peptide of the Staphylococcus epidermidis agr system
-
The agr system is conserved throughout the staphylococci, though in non-aureus species its activation by culture supernatants is rather weak, at best. Nevertheless, the autoinducing peptides of S. epidermidis are confirmed to possess the same cyclic thiolactone structure as those of S. aureus. Given that non-aureus staphylococci generally do not express the set of S. aureus virulence factors, there has yet to be a demonstration that agr actually regulates anything in these other species. In failing to address this issue, this paper leaves much to be desired.

Structure-activity analysis of the thiolactone peptides from Staphylococcus aureus responsible for autoinduction of virulence and for bacterial interference
-
in press. This paper describes an elegant solid-phase method for the synthesis of cyclic thiolactone peptides, finalizing the proof of this structure for the autoinducing peptides of S. aureus, and permitting the rapid synthesis of a large number of variants. Study of these suggests that the thiolactone structure is essential for activation but not for inhibition, that the activating peptide forms a covalent bond with its receptor and that inhibitory peptides bind to the receptor differently than activators. It also demonstrates that an inhibitory peptide can attenuate an experimental staphylococcal infection.
