Outer membrane permeability: Antimicrobials and diverse nutrients bypass porins in Pseudomonas aeruginosa. (chrisdixie.com)
Mitochondrial2
Putative mitochondrial porin (voltage-dependent anion. (ntu.edu.sg)
Mitochondrial porin , also known as the voltage-dependent anion channel (VDAC), is a multi-functional channel protein that shuttles metabolites between the mitochondria and the cytosol and implicated in cellular life and death decisions. (sdbonline.org)
Ferredoxin1
putative 4Fe-4S ferredoxin-type protein [Ensembl]. (ntu.edu.sg)
Periplasmic2
The Escherichia coli protein SurA which has been characterized as a periplasmic peptidyl-prolyl-isomerase (PPIase) and chaperon is involved in the maturation of trimeric outer membrane porins. (uni-goettingen.de)
E. coli nonspecifically transports glucose from the extracellular medium into the periplasmic space through the outer membrane porins. (encyclopedia.pub)
OmpF1
The simultanous occurence of both features is characteristic of integral outer membrane proteins and might therefore be crucial for selective substrate recognition and binding by SurA.The localisation of identified SurA binding peptides in the native structure of LamB and OmpF revealed numerous putative binding sites at the contact areas of the trimer subunits and only a few sites at membrane exposed trimer surfaces.

Transporters1
Identification of putative archaeal transporters were not included. (chrisdixie.com)
Transcriptional1
In silico analyses suggested a putative binding site for the SoxS transcriptional factor at the ompW regulatory region. (uandes.cl)
Coli1
In the last part the influence of point mutants within the greasy slide of the maltose specific porin (LamB) of E. coli were shown. (uni-wuerzburg.de)
OmpA1
Putative two domain porin with N-terminal domain homologous to 9.B.153.3.5 and a C-terminal OmpA/MotB domain. (tcdb.org)
Proteins3
Porins B and C are cell wall channel-forming proteins from Corynebacterium. (wikipedia.org)
However they are often annotated in the NCBI protein database as the DUF1551 or PF04314 family, alpha-amylase catalytic proteins, members of the Phenol_MetA-deg (MetA-pathway of phenol degradation) superfamily, signal peptide proteins and porins. (tcdb.org)
Although these proteins are listed as members of the Outer Membrane Pore-forming Protein (OMPP-I) Superfamily , it is not certain that they show sequence similarity in their putative porin domains. (tcdb.org)
Biosynthesis1
ALAD is a putative 5-aminolevulinate dehydratase involved in chlorophyll biosynthesis. (phytoab.com)
System1
In this study the expression of an outer membrane component of a putative drug efflux system of B. burgdorferi was shown for the first time. (uni-wuerzburg.de)
Exchange1
Porin B from Corynebacterium glutamicum (Brevibacterium flavum) allows the exchange of material across the mycolic acid layer, which is the protective nonpolar barrier. (wikipedia.org)
Search2
A BLAST search and a conserved domain search showed that BB0142 is a putative TolC homologue in B. burgdorferi. (uni-wuerzburg.de)
This search revealed only 13 previously unsampled putative transporter families from Cluster 2. (chrisdixie.com)
Structure1
Porin B has an alpha helical core structure consisting of four alpha-helices surrounding a nonpolar interior. (wikipedia.org)
