FunFam 64839: UDP-N-acetylglucosamine pyrophosphorylase 1

There are 5 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
UDP-N-acetylglucosamine diphosphorylase. [EC: 2.7.7.23]
UTP + N-acetyl-alpha-D-glucosamine 1-phosphate = diphosphate + UDP-N- acetyl-alpha-D-glucosamine.
  • Part of the pathway for acetamido sugar biosynthesis in bacteria and archaea.
  • The enzyme from several bacteria (e.g., Escherichia coli, Bacillus subtilis and Haemophilus influenzae) has been shown to be bifunctional and also to possess the activity of EC 2.3.1.157.
  • The enzyme from plants and animals is also active toward N-acetyl- alpha-D-galactosamine 1-phosphate (cf. EC 2.7.7.83), while the bacterial enzyme shows low activity toward that substrate.

2-alkenal reductase (NAD(P)(+)). [EC: 1.3.1.74]
A n-alkanal + NAD(P)(+) = an alk-2-enal + NAD(P)H.
  • Highly specific for 4-hydroxynon-2-enal and non-2-enal.
  • Alk-2-enals of shorter chain have lower affinities.
  • Exhibits high activities also for alk-2-enones such as but-3-en-2-one and pent-3-en-2-one.
  • Inactive with cyclohex-2-en-1-one and 12-oxophytodienoic acid.
  • Involved in the detoxification of alpha,beta-unsaturated aldehydes and ketones (cf. EC 1.3.1.102).

UDP-N-acetylgalactosamine diphosphorylase. [EC: 2.7.7.83]
UTP + N-acetyl-alpha-D-galactosamine 1-phosphate = diphosphate + UDP-N- acetyl-alpha-D-galactosamine.
  • The enzyme from plants and animals also has activity toward N-acetyl- alpha-D-glucosamine 1-phosphate (cf. EC 2.7.7.23).

UTP--glucose-1-phosphate uridylyltransferase. [EC: 2.7.7.9]
UTP + alpha-D-glucose 1-phosphate = diphosphate + UDP-glucose.

    N(6)-L-threonylcarbamoyladenine synthase. [EC: 2.3.1.234]
    L-threonylcarbamoyladenylate + adenine(37) in tRNA = AMP + N(6)-L- threonylcarbamoyladenine(37) in tRNA.
    • The enzyme is involved in the synthesis of N(6)- threonylcarbamoyladenosine(37) in tRNAs, which is found in tRNAs with the anticodon NNU, i.e. tRNA(Ile), tRNA(Thr), tRNA(Asn), tRNA(Lys), tRNA(Ser) and tRNA(Arg).
    • Formerly EC 2.6.99.4.
