... Amino Acids Proteins are very complicated moleucules. With 20 different amino acids that can be arranged in any order to make a polypeptide of up to thousands of amino acids long, their potential for variety is extraordinary. This variety allows proteins to function as exquisitely specific enzymes t ...

... Opa1 is one of three GTPases known to regulate mitochondrial fusion. When Opa1 is knocked down in cells, mitochondrial fragmentation results (Chen et al. 2005; Cipolat et al. 2004; Griparic et al. 2004; Olichon et al. 2003). To determine whether the mutation we found in Opa1 disrupts Opa1 function, ...

Magnesium transporter

This page links directly from the magnesium in biological systems page.Magnesium transporters are proteins that transport magnesium across the cell membrane. All forms of life require magnesium, yet the molecular mechanisms of Mg2+ uptake from the environment and the distribution of this vital element within the organism are only slowly being elucidated.In bacteria, Mg2+ is probably mainly supplied by the CorA protein and, where the CorA protein is absent, by the MgtE protein. In yeast the initial uptake is via the Alr1p and Alr2p proteins, but at this stage the only internal Mg2+ distributing protein identified is Mrs2p. Within the protozoa only one Mg2+ transporter (XntAp) has been identified. In metazoa, Mrs2p and MgtE homologues have been identified, along with two novel Mg2+ transport systems TRPM6/TRPM7 and PCLN-1. Finally, in plants, a family of Mrs2p homologues has been identified along with another novel protein, AtMHX.
