{"doi":"10.1128/spectrum.03094-22","title":"Outer Membrane Porin F in E. coli Is Critical for Effective Predation by <i>Bdellovibrio</i>","abstract":"Bdellovibrio bacteriovorus and like organisms (BALOs) are Gram-negative predatory bacteria that attack other Gram-negative bacteria by penetrating their periplasm and consuming them from within to obtain the nutrients necessary for the predator's growth and replication. How these predators recognize their prey, however, has remained a mystery. Here, we show that the outer membrane porin F (OmpF) in E. coli is recognized by B. bacteriovorus strain 109J and that the loss of this protein leads to severely delayed predation. However, predation of several other prey species was not dependent on the recognition of this protein or its homologues, indicating that there are other structures recognized by the predators on the prey surface that are yet to be discovered.","journal":"Microbiology Spectrum","year":2022,"id":273414,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":11,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9595,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":941427,"name":"Sumudu Upatissa","orcid":null,"position":1,"is_corresponding":false},{"id":827882,"name":"Sung-Bin Lim","orcid":"0009-0004-9147-526X","position":2,"is_corresponding":false},{"id":570710,"name":"Mohammed Dwidar","orcid":"0000-0003-1366-0393","position":3,"is_corresponding":false},{"id":940844,"name":"Robert J.
