Nucleoside-specific porin (the tsx gene of Escherichia coli) is an outer membrane protein Tsx which constitutes the receptor for colicin K and Bacteriophage T6 and functions as a substrate-specific channel […]

Delta endotoxins (δ-endotoxins also called Cry and Cyt toxins) are pore-forming toxins produced by Bacillus thuringiensis species of bacteria. They are useful for their insecticidal action.During spore formation the bacteria […]

Stannins are small proteins that consist of a single transmembrane helix an unstructured linker domain and a cytoplasmic domain. The transmembrane region contains a conserved cysteine residue (Cys32) that together […]

The major facilitator superfamily (MFS) is a class of membrane transport proteins that facilitate movement of small solutes across cell membranes in response to chemiosmotic ion gradients.

In molecular biology a saposin protein domain is a region of the saposin protein that has a certain conserved sequence or structure that defines a domain. Saposins are small lysosomal […]

Endonuclease/Exonuclease/phosphatase family is a structural domain found in the large family of proteins including magnesium dependent endonucleases and many phosphatases involved in intracellular signaling.

Animal heme-dependent peroxidases is a family of peroxidases.Peroxidases are found in bacteria fungi plants and animals. On the basis of sequence similarity a number of animal heme peroxidases can be […]

The GRAM domain is found in glucosyltransferases myotubularins and other membrane-associated proteins. The structure of the GRAM domain is similar to that found in PH domains.

K+ channel tetramerisation domain is the N-terminal cytoplasmic tetramerisation domain (T1) of voltage-gated K+ channels. It defines molecular determinants for subfamily-specific assembly of alpha-subunits into functional tetrameric channels. It is […]

Transmembrane ion channel family was defined in InterPro and Pfam as the family of tetrameric sodium potassium and calcium ion channels in which two C-terminal transmembrane helices flank a loop […]
