ike2

Profile

Name: ike2
Base Pairs: 447bp
Origin: Pseudomonas putida KT2440, genome
Properties: Immunity effector in type VI secretion system

Usage and Biology

BBa_K4028001 is a coding sequence of ike2, an immunity protein in Pseudomonas putida KT2440. Ike2 is used for protecting bacteria from type VI secretion system (T6SS). A wide range of Gram-negative bacteria have been shown to have antibacterial T6SSs, including opportunistic pathogens such as Pseudomonas aeruginosa,[4] obligate commensal species that inhabit the human gut (Bacteroides spp.),[5] and plant-associated bacteria such as Agrobacterium tumefaciens.[6] Under natural conditions, bacterial cells encoding T6SS transport effect factors with cytotoxic or antibacterial effects (amidase, glycoside hydrolyase, lipase, etc.) to recipient cells through physical contact, thus inhibiting the growth of recipient cells. Meanwhile, the bacteria encoding T6SS can translate and produce corresponding immune protein (ike2) to counteract the damage caused by toxic effector factors.[1,2,3]
