We generated a global-scale understanding of marine heteroprokaryotic functional biogeography by synthesizing genetic sequencing data with a mechanistic marine ecosystem model. We incorporated heteroprokaryotic diversity into the trait-based model along two axes: substrate lability and growth strategy. Using genetic sequences along three ocean transects, we compiled 21 heteroprokaryotic guilds and estimated their degree of optimization for rapid growth (copiotrophy). Data and model consistency indicated that gradients in grazing and substrate lability predominantly set biogeographical patterns, and we identified deep-ocean “slow copiotrophs” whose ecological interactions control the surface accumulation of dissolved organic carbon.</div>","PeriodicalId":21678,"journal":{"name":"Science","volume":"388 6749","pages":""},"PeriodicalIF":44.7,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144118301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This view has persisted for more than five decades, with any exceptions considered as special cases. However, on page 835 of this issue, Hernandez <i>et al</i>.

A growing body of work has shown that IDRs often interact with partners in a manner that does not depend on the precise order of amino acids but is instead driven by complementary chemical interactions, leading to disordered bound-state complexes. However, these chemically specific dynamic interactions are difficult to predict. In this study, we repurposed the chemical physics developed originally for molecular simulations to predict this chemical specificity between IDRs and partner proteins using protein sequence as the only input.
