FunFam 88: Polyamine aminopropyltransferase

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 5 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.

Auxin polar transport GO:0009926
The unidirectional movement of auxin in the stem from tip to base along the vector of gravity or basipetally.
1 Q9S7X6 (/IMP)
Phloem or xylem histogenesis GO:0010087
The process whose specific outcome is the progression of phloem and/or xylem over time, from formation to the mature structure. An example of this process is found in Arabidopsis thaliana.
1 Q9S7X6 (/IMP)
Xylem vessel member cell differentiation GO:0048759
The process in which a relatively unspecialized cell acquires specialized features of a vessel member cell. A vessel member cell is one of the components of a vessel in the xylem. It is a dead cell with the wall between adjacent members being variously perforated and the walls that persist variously thickened.

GO Term Annotations Evidence
Cell wall GO:0005618
The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, most prokaryotic cells and some protozoan parasites, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan; in protozoan parasites such as Giardia species, it's made of carbohydrates and proteins.
