Proteomic insights into Helcococcus kunzii in a diabetic foot ulcer‐like environment

Résumé

Abstract Purpose Helcococcus kunzii is a skin commensal, Gram‐positive bacterium, mostly isolated from infected chronic wounds. This opportunistic pathogen is usually co‐isolated with Staphylococcus aureus . The present dataset explores the production and secretion of H. kunzii bacterial virulence interacting proteins in a growth medium mimicking chronic wounds in exponential and stationary growth phases. Experimental Design The H. kunzii cellular proteome and exoproteome were assessed by analyzing three biological replicates per condition tested. Samples were analyzed using a Q‐Exactive HF mass spectrometer. Comparative and functional analyses were performed to profile the identified protein set. Results The H. kunzii ’s cellular proteome encompassed 969 proteins, among which 64 and 53 were specifically identified in the exponential and stationary phase of growth, respectively. Its exoproteome comprised 58 proteins, among which 16 and 14 were characteristic of each growth stage. Metabolic differences between the two phases of growth are discussed. Besides, the production of previously shortlisted and novel putative H. kunzii targets involved in modulating the virulence of S. aureus is investigated. Conclusion and Clinical Relevance This work, pioneering the study of H . kunzii physiology in a chronic wound‐like environment, should assist future research on this opportunistic pathogen and the search for innovative approaches for wound management.
