Nucleic Acids Res
. 2015 Mar;
43(10):e69.
PMID: 25765641
A major challenge in the field of shotgun metagenomics is the accurate identification of organisms present within a microbial community, based on classification of short sequence reads. Though existing microbial...

PMID: 19285985
Globin-coupled sensors are heme-binding signal transducers in Bacteria and Archaea in which an N-terminal globin controls the activity of a variable C-terminal domain. Here, we report that BpeGReg, a globin-coupled...

. 2008 Apr;
437:163-72.
PMID: 18433628
Globin-coupled sensors (GCSs) are multidomain proteins, consisting of an N-terminal globin domain fused to a variety of C-terminal transmitter domains. Functional classification of GCSs is based on the transmitter domain(s)...

. 2004 Dec;
99(1):23-33.
PMID: 15598488
The strategy for detecting oxygen, carbon monoxide, nitric oxide, and sulfides is predominantly through heme-based sensors utilizing either a globin domain or a PAS domain. Whereas PAS domains bind various...

PMID: 15096613
Hemoglobins are ubiquitous in Eukarya and Bacteria but, until now, have not been found in Archaea. A phylogenetic analysis of the recently revealed microbial family of globin-coupled heme-based sensors suggests...

PMID: 14527668
The recently discovered globin-coupled sensors (GCSs) are heme-containing two-domain transducers distinct from the PAS domain superfamily. We have identified an additional 22 GCSs with varying multi-domain C-terminal transmitters through a...
