Comments [?]

case <OC:Shewanella>
Function Activates KDO8N (a required 8-carbon sugar) for incorporation into bacterial lipopolysaccharide in the Shewanella genus.
Catalytic activity RHEA:49284: 8-amino-3,8-dideoxy-alpha-D-manno-octulosonate + CTP = CMP-8-amino-3,8-dideoxy-alpha-D-manno-oct-2-ulosonate + diphosphate
EC 2.7.7.90
else
Function Activates KDO (a required 8-carbon sugar) for incorporation into bacterial lipopolysaccharide in Gram-negative bacteria.
Catalytic activity RHEA:23448: 3-deoxy-alpha-D-manno-oct-2-ulosonate + CTP = CMP-3-deoxy-beta-D-manno-octulosonate + diphosphate
EC 2.7.7.38
Pathway Nucleotide-sugar biosynthesis; CMP-3-deoxy-D-manno-octulosonate biosynthesis; CMP-3-deoxy-D-manno-octulosonate from 3-deoxy-D-manno-octulosonate and CTP: step 1/1.
end case
case defined <Property:Membrane> and <Property:Membrane=2>
Pathway Bacterial outer membrane biogenesis; lipopolysaccharide biosynthesis.
end case
