1.17.9.1	malfunction	using a gene-knockout it is shown that PCMH-encoding gene pchF is necessary for the catabolism of 2,4-xylenol	726788	
1.17.9.1	metabolism	PCMH is a key enzyme responsible for the catabolism of p-cresol via the protocatechuate ortho pathway, pathway overview	-, 715044	
1.17.9.1	metabolism	the enzyme is necessary for 2,4-xylenol catabolism	-, 744141	
1.17.9.1	additional information	transcriptional regulation of the pchACXF operon by PchR, a putative sigma54-dependent regulator, overview. Phenol does not activate the regulator of PC24, and both regulators respond similarly to p-cresol	-, 715044
