General Information

General Information Comment Organism
malfunction Pseudomonas aeruginosa acpP1 deletion is lethal, while disruption of acpP2 or acpP3 in the Pseudomonas aeruginosa genome allowa mutant strains to grow like the wild-type strain. AcpP1 functions in fatty acid biosynthesis with the enzyme acyl-ACP synthetase, acpP2 and acpP3 do not play roles in the fatty acid synthetic pathway. Replacement of acpP1 with Escherichia coli acpP reduces the ability of Pseudomonas aeruginosa to produce some exo-products and abolished swarming motility Pseudomonas aeruginosa
physiological function only the acpP1 gene can restore growth in the Escherichia coli acpP mutant strain CY1877, while genes acpP2 and acpP3 are ineffective, neither AcpP2 nor AcpP3 can act as a substrate for synthesis of N-acylhomoserine lactones molecules in vivo. Gene acpP1 is essential for Pseudomonas aeruginosa growth Pseudomonas aeruginosa
