2.3.1.129 | evolution |
the enzymes in early lipid A biosynthesis are highly conserved in gram-negative pathogens. LpxA and LpxD are structurally homologous possessing the unique left-handed beta-helix fold, which stems from an extensive hexapeptide repeat motif in their respective primary amino acid sequences |

2.3.1.129 | evolution |
the overall structure of AtLpxA is very similar to that of Escherichia coli LpxA, EcLpxA, with an alpha-helical-rich C-terminus and characteristic N-terminal left-handed parallel beta-helix. All key catalytic and chain length determining residues of EcLpxA are conserved in AtLpxA,but AtLpxA has an additional coil and loop added to the N-terminal left-handed parallel beta-helix not seen in EcLpxA |

2.3.1.129 | metabolism |
acyltransferases LpxA and LpxD catalyze functionally similar acylations of their respective UDP-glucosamine-based substrates using R-3-hydroxymyristoyl-ACP as the acyl donor in the Kdo2-lipid A biosynthesis in Escherichia coli |
