## Executive GIST (TL;DR)
- β-lactamases are central enzymes in bacterial resistance to **β-lactam antibiotics**, and are frequently used as an example of cooperative resistance in microbiology. - Their cooperative effects arise because they degrade antibiotic molecules, which can detoxify the environment not only for the producing cell but also for neighbouring cells, generating cross-protection. - Extracellular action of β-lactamases, including release beyond the producing cell, expands the spatial range of detoxification and increases benefits to non-producers. - Non-producer cells can exploit these benefits, creating potential **cooperator–cheat dynamics** within populations. - Recent work shows substantial variation in how much β-lactamase-mediated resistance is shared, driven by mechanistic and ecological details. - Key mechanistic factors affecting sharing include subcellular localisation of the enzyme, **membrane anchoring**, and packaging in **outer-membrane vesicles (OMVs)**. - Ecological and population factors such as **population structure** influence whether benefits remain local (private) or are broadly shared (cooperative). - The authors propose that β-lactamase-mediated resistance exists on a continuum from private to cooperative, not as a strict category. - Recognising this continuum matters for understanding the evolution of antimicrobial resistance and for predicting treatment outcomes in clinical and ecological contexts. - The review synthesises these themes and highlights the need to incorporate variation in sharing when modelling resistance evolution or designing interventions.

The cooperative aspect of their action arises from specific details of their action and location. Firstly, they degrade β-lactam antibiotic molecules, which detoxifies the environment for neighbouring cells as well as self, and secondly, they can act extracellularly, increasing the spatial range of this detoxifying effect and the benefit to neighbouring cells. Non-producer cells are able to take advantage of cross-protection from their cooperative neighbours and cooperator-cheat dynamics can emerge. However, mechanistic and ecological details determine the extent to which β-lactamase evolves as a result of its social action, or from private benefits to the producing cell. In the present review, we highlight recent work that reveals substantial variation in the extent to which β-lactamase-mediated resistance is shared among cells, focusing on subcellular localisation, membrane anchoring, outer-membrane vesicles, and population structure. We argue that β-lactamase spans a continuum from private to cooperative, and that recognising this variation is important both for understanding the evolution of antimicrobial resistance and for predicting treatment outcomes. **Keywords:** antibiotic resistance; cooperation; social microbiology; β-lactamase. © 2026 The Author(s).
