FunFam 76846: Cystine transporter subunit

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 2 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

L-cystine transmembrane transporter activity GO:0015184
Enables the transfer of L-cystine from one side of a membrane to the other.
1 P0AEM9 (/IDA)
Cysteine transmembrane transporter activity GO:0033229
Enables the transfer of cysteine from one side of the membrane to the other.
1 P0AEM9 (/IDA)

There are 2 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
L-cystine transport GO:0015811
The directed movement of L-cystine (also known as dicysteine) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
1 P0AEM9 (/IDA)
Cysteine transport GO:0042883
The directed movement of cysteine into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
1 P0AEM9 (/IDA)

There are 2 GO terms relating to "cellular component"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Outer membrane-bounded periplasmic space GO:0030288
The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall.
1 P0AEM9 (/IDA)
ATP-binding cassette (ABC) transporter complex GO:0043190
A complex for the transport of metabolites into and out of the cell, typically comprised of four domains; two membrane-associated domains and two ATP-binding domains at the intracellular face of the membrane, that form a central pore through the plasma membrane. Each of the four core domains may be encoded as a separate polypeptide or the domains can be fused in any one of a number of ways into multidomain polypeptides. In Bacteria and Archaebacteria, ABC transporters also include substrate binding proteins to bind substrate external to the cytoplasm and deliver it to the transporter.
