FunFam 96012: Probable sucrose-phosphate synthase 4

There are 3 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
Sucrose-phosphate synthase. [EC: 2.4.1.14]
UDP-glucose + D-fructose 6-phosphate = UDP + sucrose 6(F)-phosphate.
  • The enzyme from Synechocystis sp. strain PCC 6803 is not specific for UDP-glucose as it can use ADP-glucose and, to a lesser extent, GDP- glucose as substrates.
  • The enzyme from rice leaves is activated by glucose 6-phosphate but that from cyanobacterial species is not.
  • While the reaction catalyzed by this enzyme is reversible, the enzyme usually works in concert with EC 3.1.3.24 to form sucrose, making the above reaction essentially irreversible.
  • The F in sucrose 6(F)-phosphate is used to indicate that the fructose residue of sucrose carries the substituent.

Glutamine N-phenylacetyltransferase. [EC: 2.3.1.14]
Phenylacetyl-CoA + L-glutamine = CoA + alpha-N-phenylacetyl-L-glutamine.

    Amidophosphoribosyltransferase. [EC: 2.4.2.14]
    5-phospho-beta-D-ribosylamine + diphosphate + L-glutamate = L-glutamine + 5-phospho-alpha-D-ribose 1-diphosphate + H(2)O.
