FunFam 53051: Glucan endo-1,3-beta-glucosidase 1

There are 7 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
Glucan endo-1,3-beta-D-glucosidase. [EC: 3.2.1.39]
Hydrolysis of (1->3)-beta-D-glucosidic linkages in (1->3)-beta-D-glucans.
  • Very limited action on mixed-link (1->3,1->4)-beta-D-glucans.
  • Hydrolyzes laminarin, paramylon and pachyman.
  • Different from EC 3.2.1.6.

Histidine kinase. [EC: 2.7.13.3]
ATP + protein L-histidine = ADP + protein N-phospho-L-histidine.
  • This entry has been included to accommodate those protein-histidine kinases for which the phosphorylation site has not been established (i.e. either the pros- or tele-nitrogen of histidine).
  • A number of histones can act as acceptor.

Glucan 1,3-beta-glucosidase. [EC: 3.2.1.58]
Successive hydrolysis of beta-D-glucose units from the non-reducing ends of (1->3)-beta-D-glucans, releasing alpha-glucose.
  • Acts on oligosaccharides, but very slowly on laminaribiose.

Licheninase. [EC: 3.2.1.73]
Hydrolysis of (1->4)-beta-D-glucosidic linkages in beta-D-glucans containing (1->3)- and (1->4)-bonds.
  • Acts on lichenin and cereal beta-D-glucans, but not on beta-D-glucans containing only 1,3- or 1,4-bonds.

TRNA (guanine(37)-N(1))-methyltransferase. [EC: 2.1.1.228]
S-adenosyl-L-methionine + guanine(37) in tRNA = S-adenosyl-L-homocysteine + N(1)-methylguanine(37) in tRNA.
  • This enzyme is important for the maintenance of the correct reading frame during translation.
  • Unlike TrmD from Escherichia coli, which recognizes the G(36)pG(37) motif preferentially, the human enzyme (encoded by TRMT5) also methylates inosine at position 37.
  • Formerly EC 2.1.1.31.

Endo-1,3(4)-beta-glucanase. [EC: 3.2.1.6]
Endohydrolysis of (1->3)- or (1->4)-linkages in beta-D-glucans when the glucose residue whose reducing group is involved in the linkage to be hydrolyzed is itself substituted at C-3.
  • Substrates include laminarin, lichenin and cereal D-glucans.
  • Different from EC 3.2.1.39 and EC 3.2.1.52.
 2 C5IDR4 C5IDR4
Glycerol-3-phosphate dehydrogenase (NAD(+)). [EC: 1.1.1.8]
sn-glycerol 3-phosphate + NAD(+) = glycerone phosphate + NADH.
  • Also acts on propane-1,2-diol phosphate and glycerone sulfate (but with a much lower affinity).
