FunFam 31392: Bifunctional glutamate--cysteine ligase/glutathion...

There are 6 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
Glutathione synthase. [EC: 6.3.2.3]
ATP + gamma-L-glutamyl-L-cysteine + glycine = ADP + phosphate + glutathione.

    (552 more...)
    Glutamate--cysteine ligase. [EC: 6.3.2.2]
    ATP + L-glutamate + L-cysteine = ADP + phosphate + gamma-L-glutamyl-L- cysteine.
    • Can use L-aminohexanoate in place of glutamate.

    Cyanophycin synthase (L-aspartate-adding). [EC: 6.3.2.29]
    ATP + (L-Asp(4-L-Arg))(n) + L-Asp = ADP + phosphate + (L-Asp(4-L- Arg))(n)-L-Asp.
    • Both this enzyme and EC 6.3.2.30 are required for the elongation of cyanophycin, which is a protein-like cell inclusion that is unique to cyanobacteria and acts as a temporary nitrogen store.
    • Both enzymes are found in the same protein but have different active sites.
    • Both L-Asp and L-Arg must be present before either enzyme will display significant activity.

    Cyanophycin synthase (L-arginine-adding). [EC: 6.3.2.30]
    ATP + (L-Asp(4-L-Arg))(n)-L-Asp + L-Arg = ADP + phosphate + (L-Asp(4-L- Arg))(n+1).
    • Both this enzyme and EC 6.3.2.29 are required for the elongation of cyanophycin, which is a protein-like cell inclusion that is unique to cyanobacteria and acts as a temporary nitrogen store.
    • Both enzymes are found in the same protein but have different active sites.
    • Both L-Asp and L-Arg must be present before either enzyme will display significant activity.
    • Canavanine and lysine can be incoporated into the polymer instead of arginine.

    D-alanine--D-alanine ligase. [EC: 6.3.2.4]
    ATP + 2 D-alanine = ADP + phosphate + D-alanyl-D-alanine.
    • Involved with EC 6.3.2.7 or EC 6.3.2.13, EC 6.3.2.8, EC 6.3.2.9 and EC 6.3.2.10 in the synthesis of a cell-wall peptide.

    UDP-N-acetylmuramoyl-L-alanyl-D-glutamate--2,6-diaminopimelate ligase. [EC: 6.3.2.13]
    ATP + UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-D-glutamate + meso-2,6- diaminoheptanedioate = ADP + phosphate + UDP-N-acetyl-alpha-D-muramoyl-L- alanyl-D-gamma-glutamyl-meso-2,6-diaminoheptanedioate.
    • Involved in the synthesis of a cell-wall peptide.
    • This enzyme adds diaminopimelate in Gram-negative organisms and in some Gram-positive organisms; in others EC 6.3.2.7 adds lysine instead.
    • It is the amino group of the L-center of the diaminopimelate that is acylated.
