Authors: Søren K Amstrup / Sui Ching Ong / Nicholas Sofos / Jesper L Karlsen / Ragnhild B Skjerning / Thomas Boesen / Jan J Enghild / Bjarne Hove-Jensen / Ditlev E Brodersen / ![]() Abstract: In Escherichia coli, the 14-cistron phn operon encoding carbon-phosphorus lyase allows for utilisation of phosphorus from a wide range of stable phosphonate compounds containing a C-P bond. As part ...In Escherichia coli, the 14-cistron phn operon encoding carbon-phosphorus lyase allows for utilisation of phosphorus from a wide range of stable phosphonate compounds containing a C-P bond. As part of a complex, multi-step pathway, the PhnJ subunit was shown to cleave the C-P bond via a radical mechanism, however, the details of the reaction could not immediately be reconciled with the crystal structure of a 220 kDa PhnGHIJ C-P lyase core complex, leaving a significant gap in our understanding of phosphonate breakdown in bacteria. Here, we show using single-particle cryogenic electron microscopy that PhnJ mediates binding of a double dimer of the ATP-binding cassette proteins, PhnK and PhnL, to the core complex. ATP hydrolysis induces drastic structural remodelling leading to opening of the core complex and reconfiguration of a metal-binding and putative active site located at the interface between the PhnI and PhnJ subunits. #1: ![]() Title: Structural remodelling of the carbon-phosphorus lyase machinery by a dual ABC ATPase Authors: Amstrup SK / Sofos N / Karlsen JL / Skjerning RB / Boesen T / Enghild JJ / Hove-Jensen B / Brodersen DE | |||||||||
