Background:
- Membrane proteins play vital roles in cellular transport and metabolism.
- Understanding specific transporter functions is key to elucidating microbial metabolic pathways.
Purpose of the Study:
- To investigate the physiological function of membrane protein RHOGL009301 in Rhodococcus sp. R04.
- To determine the relationship between RHOGL009301 and benzoate transport.
Main Methods:
- Gene fusion and expression of RHOGL009301 with green fluorescent protein in Rhodococcus erythropolis.
- Gene knockout of RHOGL009301 via homologous recombination.
- Comparative growth analysis of wild and deficient strains on various carbon sources.
- Metabolite analysis using High-Performance Liquid Chromatography (HPLC).
Main Results:
- RHOGL009301 was localized to the cell membrane.
- The RHOGL009301-deficient strain showed reduced biomass and growth rate on benzoate and biphenyl.
- HPLC analysis confirmed that RHOGL009301 deletion inhibited benzoate transport.

Protein Transport to the Inner Chloroplast Membrane
2.5K
Proteins targeted to the inner chloroplast membrane, or plastid proteins, are transported by two general pathways: the stop-transfer and the re-insertion or post-import pathways. Most plastid proteins carry N-terminal transit sequences and internal import sequences targeting it to the specific chloroplast subcompartment. Proteins targeted by the stop-transfer pathway have internal hydrophobic sequences that inhibit their translocation into the stroma. As a result, these precursors are arrested...

Protein Transport into the Inner Mitochondrial Membrane
5.0K
Nuclear encoded mitochondrial precursors are imported to the inner membrane in a multistep process involving two separate translocons, TIM22 and TIM23. TIM23 is a cation-selective pore that remains closed by the N terminal segment of the protein. Negative charges on the TIM23 act as a receptor for the incoming precursor, pulling the positively charged matrix-targeting sequence for peptide insertion and translocation.
Transport of mitochondrial precursors across the TIM23 channel is driven by...

Protein Transport to the Outer Chloroplast Membrane
2.4K
Chloroplast outer membrane proteins encoded by the nucleus are synthesized in the cytosol. Soon after synthesis, they bind cytosolic factors such as 14-3-3 protein and the Hsp70 chaperones that keep these precursors in an unfolded state until their translocation.
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.

Introduction to Membrane Proteins
81.6K
The cell membrane, or plasma membrane, is an ever-changing landscape. It is described as a fluid mosaic where various macromolecules are embedded in the phospholipid bilayer. Among the macromolecules are proteins. The protein content varies across cell types. For example, mitochondrial inner membranes contain ~76% protein content, while myelin contains ~18% protein content. Individual cells contain many types of membrane proteins—red blood cells contain over 50—and different cell...

Membrane Transporters
18.2K
Transporters are essential membrane transport proteins with functions related to cell nutrition, homeostasis, communication, etc. Approximately 7% of all genes in the human genome code for transporters or transporter-related proteins.
Transporters are mainly composed of alpha-helices, built from bundles of ten or more helices traversing the plasma membrane. The solute-binding sites are located midway, where some of the helices are broken or distorted, making space for the binding site through...

The Significance of Membrane Transport
42.6K
The transport of solutes across the cell membrane is essential for metabolic processes, like maintaining cell size and volume, generating the action potential, exchanging nutrients and gases, etc. Membrane transport can be either passive or active. It can be simple diffusion, facilitated, or mediated transport aided by transport proteins such as transporters and channels.
Transporters facilitate either an active or passive movement of solutes. They can allow a single-molecule transport down its...
