β-Barrel Membrane Protein Assembly by the Bam Complex

Annual Review of Biochemistry, 2011
β-barrel membrane proteins perform important functions in the outer membranes (OMs) of Gram-negative bacteria and of the mitochondria and chloroplasts of eukaryotes. The protein complexes that assemble these proteins in their respective membranes have been identified and shown to contain a component that has been conserved from bacteria to humans.

Global stability analysis for delayed complex-valued BAM neural networks

Neurocomputing, 2016
This paper investigates the stability criteria for complex-valued bidirectional associative memory (BAM) with time delay. Firstly, based on the Lyapunov function method and mathematical analysis technique, sufficient conditions for the existence of unique equilibrium, and global asymptotic stability of the equilibrium are derived by separating complex ...

Substrate-dependent arrangements of the subunits of the BAM complex determined by neutron reflectometry

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2021
In Gram-negative bacteria, the β-barrel assembly machinery (BAM) complex catalyses the assembly of β-barrel proteins into the outer membrane, and is composed of five subunits: BamA, BamB, BamC, BamD and BamE. Once assembled, - β-barrel proteins can be involved in various functions including uptake of nutrients, export of toxins and mediating host ...

The Bam (Omp85) complex is involved in secretion of the autotransporter haemoglobin protease

Microbiology, 2009
Autotransporters are large virulence factors secreted by Gram-negative bacteria. They are synthesized with a C-terminal domain that forms aβ-barrel pore in the outer membrane implicated in translocation of the upstream ‘passenger’ domain across the outer membrane.

Dissipativity analysis of complex-valued BAM neural networks with time delay

Neural Computing and Applications, 2017
This paper is concerned with dissipativity analysis of complex-valued bidirectional associative memory (BAM) neural networks (NNs) with time delay. Some novel sufficient conditions that guarantee the dissipativity of complex-valued BAM neural networks (CVBNNs) are obtained by using the inequality techniques, Halanay inequality, and upper right Dini ...

Studying assembly of the BAM complex in native membranes by cellular solid-state NMR spectroscopy

Journal of Structural Biology, 2019
Significant progress has been made in obtaining structural insight into the assembly of the β-barrel assembly machinery complex (BAM). These crystallography and electron microscopy studies used detergent as a membrane mimetic and revealed structural ...

Structure of the BAM complex and its implications for biogenesis of outer-membrane proteins

Nature Structural & Molecular Biology, 2016
In Gram-negative bacteria, the assembly of β-barrel outer-membrane proteins (OMPs) requires the β-barrel-assembly machinery (BAM) complex. We determined the crystal structure of the 200-kDa BAM complex from Escherichia coli at 3.55-Å resolution. The structure revealed that the BAM complex assembles into a hat-like shape, in which the BamA β-barrel ...

Finite-Time Stability for Delayed Complex-Valued BAM Neural Networks

Neural Processing Letters, 2017
This paper studies the finite-time stability problem of complex-valued BAM neural networks with time delay. Firstly, based on a more suitable assumption for the complex-valued activation functions of the considered system, a tractable entire real-valued system is formed.

Expression, Purification, and Screening of BamE, a Component of the BAM Complex, for Structural Characterization

2015
In Gram-negative bacteria, integral outer membrane β-barrel proteins (OMP) are assembled by the β-barrel assembly machine complex, or BAM complex. This complex includes the essential components BamA, an OMP composed of a carboxyl terminal β-barrel domain and five polypeptide transport-associated domains (POTRA), and the lipoprotein BamD. In Escherichia

Fixed‐time synchronization for complex‐valued BAM neural networks with time delays

Asian Journal of Control, 2019
AbstractIn this paper, the fixed‐time synchronization for complex‐valued bidirectional associative memory (BAM) neural networks with time delays is studied. Based on the fixed‐time stability, the Lyapunov functional method and some inequality techniques, a new criterion is presented to guarantee that the addressed systems achieve synchronization in ...
