FunFam 24887: Pyridoxal 5'-phosphate synthase subunit PdxT

There are 2 EC terms in this cluster

Please note: EC 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.

Note: 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.

EC Term Annotations Evidence
Glutaminase. [EC: 3.5.1.2]
L-glutamine + H(2)O = L-glutamate + NH(3).

    Pyridoxal 5'-phosphate synthase (glutamine hydrolyzing). [EC: 4.3.3.6]
    D-ribose 5-phosphate + D-glyceraldehyde 3-phosphate + L-glutamine = pyridoxal 5'-phosphate + L-glutamate + 3 H(2)O + phosphate.
    • The ammonia is provided by the glutaminase subunit and channeled to the active site of the lyase subunit by a 100 A tunnel.
    • The enzyme can also use ribulose 5-phosphate and dihydroxyacetone phosphate.
    • The enzyme complex is found in aerobic bacteria, archeae, fungi and plants.
