FunFam 134: L-cysteine:1D-myo-inositol 2-amino-2-deoxy-alpha-D...

There are 1 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
L-cysteine:1D-myo-inositol 2-amino-2-deoxy-alpha-D-glucopyranoside ligase. [EC: 6.3.1.13]
1-O-(2-amino-2-deoxy-alpha-D-glucopyranosyl)-1D-myo-inositol + L-cysteine + ATP = 1-O-(2-(L-cysteinamido)-2-deoxy-alpha-D-glucopyranosyl)-1D-myo- inositol + AMP + diphosphate.
  • This enzyme is a key enzyme in the biosynthesis of mycothiol, a small molecular weight thiol found in Mycobacteria spp. and other actinomycetes.
  • Mycothiol plays a fundamental role in these organisms by helping to provide protection from the effects of reactive oxygen species and electrophiles, including many antibiotics.
  • The enzyme may represent a novel target for new classes of antituberculars.
  • Formerly EC 6.1.1.n1.
