Spectrin repeat
Spectrin repeats are found in several proteins involved in cytoskeletal structure. These include spectrin alpha-actinin dystrophin and more recently the plakin family. The spectrin repeat forms a three-helix bundle. These […]
SecY protein
The SecY protein is the main transmembrane subunit of the eubacterial Sec or Type II secretory pathway and a protein-secreting ATPase complex also known as a translocon. Secretion of some […]
Beta defensin
Beta defensins are a family of mammalian defensins. The beta defensins are antimicrobial peptides implicated in the resistance of epithelial surfaces to microbial colonization.Defensins are 2-6 kDa cationic microbicidal peptides […]
Alpha defensin
Alpha defensins are a family of mammalian defensin peptides.Defensins are 2-6 kDa cationic microbicidal peptides active against many Gram-negative and Gram-positive bacteria fungi and enveloped viruses containing three pairs of […]
Glycoside hydrolase family 1
Glycoside hydrolase family 1 is a family of glycoside hydrolases.Glycoside hydrolases EC 3.2.1. are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates or […]
Pentatricopeptide repeat
The pentatricopeptide repeat (PPR) is a 35-amino acid sequence motif. Pentatricopeptide repeat containing proteins are a family of proteins commonly found in the plant kingdom. They are distinguished by the […]
Major intrinsic proteins
Major intrinsic proteins are a large family of transmembrane protein channels that are grouped together on the basis of sequence similarities. Proteins from this family exhibit essentially two distinct types […]
Sodium:neurotransmitter symporter
Sodium:neurotransmitter symporters is a family of neurotransmitter transporters.Neurotransmitter transport systems are responsible for the release re-uptake and recycling of neurotransmitters at synapses.High affinity transport proteins found in the plasma membrane […]
Replication protein A
Replication protein A (RPA) is a protein that binds single-stranded DNA in eukaryotic cells. During DNA replication RPA prevents single-stranded DNA (ssDNA) from winding back on itself or from forming […]
