Polyprenyl synthetase
Polyprenyl synthetases are a class of enzymes responsible for synthesis of isoprenoids. Isoprenoid compounds are synthesized by various organisms. For example in eukaryotes the isoprenoid biosynthetic pathway is responsible for […]
Influenza virus matrix protein 2
Matrix protein 2 of Influenza virus is a single-spanning transmembrane protein. It is expressed on the infected cell surface and incorporated into virions where it is a minor component. The […]
Proton-pumping pyrophosphatase
Two types of inorganic diphosphatase very different in terms of both amino acid sequence and structure have been characterised to date: soluble and transmembrane proton-pumping pyrophosphatases (sPPases and H(+)-PPases respectively). […]
Phosphate-selective porin
Phosphate-selective porins are a family of outer bacterial membrane proteins. These are anion-specific porins the binding site of which has a higher affinity for phosphate than chloride ions. Porin O […]
Oligogalacturonate-specific porin
Oligogalacturonate-specific porins (KdgM) are a family of outer bacterial membrane proteins from Erwinia chrysanthemi. The phytopathogenic Gram-negative bacteria E. chrysanthemi secretes pectinases which are able to degrade the pectic polymers […]
Outer membrane polysaccharide transporter
The extracellular polysaccharide colanic acid (CA) is produced by species of the family Enterobacteriaceae. In Escherichia coli (strain K12) the CA cluster comprises 19 genes. The wzx gene encodes a […]
Phage major coat protein
In molecular biology a phage major coat protein is an alpha-helical protein that forms a viral envelope of filamentous bacteriophages. These bacteriophages are flexible rods about one to two micrometres […]
Prokaryotic ubiquitin-like protein
Prokaryotic ubiquitin-like protein (Pup) – functional analog of ubiquitin found in prokaryote (Mycobacterium tuberculosis). Serves the same function although the enzymology of ubiquitylation and pupylation is different. In contrast to […]
Mercury transporter
Mercury transporter (MerF) is a transmembrane bacterial transporter of mercury ions. It has two vicinal pairs of cysteine residues which are involved in the transport of Hg(II) across the membrane […]
