FunFam 79258: Acyl-[acyl-carrier-protein]--UDP-N-acetylglucosami...

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
Acyl-[acyl-carrier-protein]--UDP-N-acetylglucosamine O-acyltransferase. [EC: 2.3.1.129]
(R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] + UDP-N-acetyl-alpha-D- glucosamine = [acyl-carrier-protein] + UDP-3-O-(3-hydroxytetradecanoyl)- N-acetyl-alpha-D-glucosamine.
  • Involved with EC 2.4.1.182 and EC 2.7.1.130 in the biosynthesis of the phosphorylated glycolipid, lipid A, in the outer membrane of Escherichia coli.

3-hydroxyacyl-[acyl-carrier-protein] dehydratase. [EC: 4.2.1.59]
A (3R)-3-hydroxyacyl-[acyl-carrier protein] = a trans-2-enoyl-[acyl- carrier protein] + H(2)O.
  • This enzyme is responsible for the dehydration step of the dissociated (type II) fatty-acid biosynthesis system that occurs in plants and bacteria.
  • The enzyme uses fatty acyl thioesters of ACP in vivo.
  • Different forms of the enzyme may have preferences for substrates with different chain length.
  • For example, the activity of FabZ, the ubiquitous enzyme in bacteria, decreases with increasing chain length.
  • Gram-negative bacteria that produce unsaturated fatty acids, such as Escherichia coli, have another form (FabA) that prefers intermediate chain length, and also catalyzes EC 5.3.3.14.
  • Despite the differences both forms can catalyze all steps leading to the synthesis of palmitate (C16:0).
  • FabZ, but not FabA, can also accept unsaturated substrates.
  • Formerly EC 4.2.1.58, EC 4.2.1.60 and EC 4.2.1.61.

Lipid-A-disaccharide synthase. [EC: 2.4.1.182]
UDP-2-N,3-O-bis((3R)-3-hydroxytetradecanoyl)-alpha-D-glucosamine + 2-N,3- O-bis((3R)-3-hydroxytetradecanoyl)-alpha-D-glucosaminyl 1-phosphate = UDP + 2-N,3-O-bis((3R)-3-hydroxytetradecanoyl)-beta-D-glucosaminyl- (1->6)-2-N,3-O-bis((3R)-3-hydroxytetradecanoyl)-alpha-D-glucosaminyl 1-phosphate.
  • Involved with EC 2.3.1.129 and EC 2.7.1.130 in the biosynthesis of the phosphorylated glycolipid, lipid A, in the outer membrane of Escherichia coli.
