The complexity, challenges and benefits of comparing two transporter classification systems in TCDB and Pfam
2015
Briefings in Bioinformatics
Two such databases are the Transporter Classification Database (TCDB) and the Protein family (Pfam) database. ...
As part of a long-term endeavor to improve consistency between the two classification systems, we have compared transporter annotations in the two databases to understand the rationale for differences ...
The examples presented in this contribution illustrate the complexity of comparing two resources such as TCDB and Pfam. ...

Genomic Inventory and Transcriptional Analysis of Medicago truncatula Transporters
2009
Plant Physiology
To initiate and support systematic characterization of transporters in the model legume Medicago truncatula, we identified 3,830 transporters and classified 2,673 of these into 113 families and 146 subfamilies ...
The data presented here are a unique resource for the selection and functional characterization of legume transporters. ...
In the following paragraphs, we discuss some of these genes in the context of what is known about transport and transporters in the two types of symbiosis. ...

Harvesting of Prebiotic Fructooligosaccharides by Nonbeneficial Human Gut Bacteria
2020
mSphere
In this study, we established a new strategy to profile the specificity of oligosaccharide transporters, combining microbiomics, genetic locus and strain engineering, and state-of-the art metabolomics. ...
Based on these developments, we identified and characterized, at the molecular level, a fructooligosaccharide transporting phosphotransferase system, which constitutes a biomarker of diet and gut pathology ...
For transporter classification, we recommend the continued use of the TCDB, which is a mine of information for these proteins, but with caution with respect to the level of classification. ...

Exploring the transportome of the biosurfactant producing yeast Starmerella bombicola
2022
BMC Genomics
Doing this, we could experimentally confirm the transporters participating in the efflux of medium chain fatty alcohols, particularly decanol and undecanol, and identify a second sophorolipid transporter ...
We conducted an analysis of this family by creating deletion mutants to understand their role in the export of hydrophobic compounds, antibiotics and sophorolipids. ...

Protein Structure Annotation Resources
[chapter]
2014
Msphere
Therefore, to maximize the amount of information garnered from the genes, proteins, and structures we do study, annotations are captured in the hopes that they may apply to similar (homologous) proteins ...
Since the 3-D structure of proteins are ultimately responsible for most actions in the cell, this review will focus on protein structure annotation resources that aim to explain a ...
