2.3.1.191 (3R)-3-hydroxylauroyl-methylphosphopantetheine competitive inhibitor with respect to UDP-3-O-((3R)-3-hydroxymyristoyl)-alpha-D-glucosamine and an uncompetitive inhibitor with respect to (3R)-3-hydroxymyristoyl-[acyl-carrier protein] 26623 2.3.1.191 (3R)-3-hydroxylauroylmethylphosphopantetheine uncompetitive inhibitor against (3R)-3-hydroxymyristoyl-[acyl-carrier protein] and a competitive inhibitor against UDP-3-O-((3R)-3-hydroxymyristoyl)-alpha-D-glucosamine 151290 2.3.1.191 (3R)-3-hydroxymyristoyl-[acyl-carrier protein] - 2623 2.3.1.191 4-(2-chlorophenyl)-3-hydroxy-7,7-dimethyl-2-phenyl-7,8-dihydro-2H-pyrazolo[3,4-b]quinolin-5(6H)-one - 247250 2.3.1.191 acyl-carrier protein competitive inhibitor with respect to (3R)-3-hydroxymyristoyl-[acyl-carrier protein] and a noncompetitive inhibitor with respect to UDP-3-O-((3R)-3-hydroxymyristoyl)-alpha-D-glucosamine 1134 2.3.1.191 Ca2+ inhibition is overcome by the addition of excess (3R)-3-hydroxymyristoyl-[acyl-carrier protein] 15 2.3.1.191 Mg2+ - 6 2.3.1.191 additional information divalent cations inhibit (3R)-3-hydroxymyristoyl-[acyl-carrier protein]-dependent acylation but not (3R)-3-hydroxylauroylmethylphosphopantetheine-dependent acylation, indicating that the acidic recognition helix of (3R)-3-hydroxymyristoyl-[acyl-carrier protein] contributes to binding; Na+ and K+ ions do not inhibit LpxD activity 2 2.3.1.191 RJPXD33 i.e. TNLYMLPKWDIP, peptide inhibitor, binds to both UDP-N-acetylglucosamine acyltransferase (LpxA, EC 2.3.1.129) and UDP-3-O-(acyl)-glucosamine acyltransferase. Comparison with binding to LpxA suggests overlap with the acyl-phosphopantetheine arm of acyl-ACP, thereby inhibiting acyl-ACP from binding to LpxD. RJPXD33 binds to LpxD without the prior binding of other ligands 87732 2.3.1.191 TNLYMLPKWDIP-NH2 i.e. peptide RJPXD33 247251
