Abstract Homarine (N-methylpicolinic acid) is a ubiquitous marine metabolite produced by phytoplankton and noted for its infochemical properties among marine animals, yet its microbial degradation pathways are uncharacterized. Here we identify a conserved operon (homABCDER) that mediates homarine catabolism in bacteria using comparative transcriptomics, mutagenesis and targeted knockouts.

Introduction Click to copy section linkSection link copied! The production, transformation, transport, and accumulation of organic matter (OM) throughout Earth’s biosphere play a central role in regulating the global carbon cycle and shaping ecosystem food webs. (1,2) Dissolved organic matter (DOM) is particularly important when considering exchanges of OM across land-river-ocean interfaces and transformations that occur as DOM undergoes biotic and abiotic reworking within and across ecosystems.

1 Introduction Annually, marine phytoplankton fix up to 50 billion tons of carbon (Falkowski 1994), with roughly half of this carbon being metabolised by marine bacteria (Azam et al. 1983). Freshly synthesised small biomolecules, known as metabolites, are among the most readily used compounds, playing an important role in fostering taxa interdependencies that structure microbial communities (Poretsky et al. 2010; Vorobev et al. 2018; Boysen et al. 2022; Moran et al. 2022).
