32097726-8	2020	IC50 values were determined to be 0.018 and 0.029 mM for potato PPO with curcumin and quercetin inhibitors with catechol as a substrate, respectively.	catechol	112-120	catechol oxidase B, chloroplastic	Solanum tuberosum	64-67	
30209938-2	2018	The aim of this study was to develop surface-enhanced Raman scattering (SERS) approach for accurate determination of PPO activity in fruit and vegetables using the reduction in SERS intensity of catechol in reaction medium.	catechol	195-203	catechol oxidase B, chloroplastic	Solanum tuberosum	117-120	
30209938-3	2018	Within a certain catechol concentration, when a purified PPO solution was analyzed, the reduction in SERS intensity (Delta I) was linear to PPO activity ( Ec) in a wide range of 500-50 000 U/L, and a linear regression equation of log Delta I/Delta t = 0.6223 log Ec + 0.8072, with a correlation coefficient of 0.9689 and a limit of detection of 224.65 U/L, was obtained.	catechol	17-25	catechol oxidase B, chloroplastic	Solanum tuberosum	57-60

17417695-2	2007	Under optimized conditions (formaldehyde 20 mg/ml, PPO 4 mg/ml and pH 7.0), the activity of immobilized PPO was 1370 U/g and its Km value for catechol was 12 mM at 25 degrees C. The highest activity of immobilized enzyme was at pH 7.4.	catechol	142-150	catechol oxidase B, chloroplastic	Solanum tuberosum	104-107	
34681535-7	2021	AA only slows mechanism-based inactivation of PPO induced by catechol, possibly owing to the prevention of quinone formation.	catechol	61-69	catechol oxidase B, chloroplastic	Solanum tuberosum	46-49	
34681535-9	2021	The problem associated with AA in PPO assay could be circumvented by using ascorbate oxidase to remove AA when catechol is the primary substrate or by using chlorogenic acid as the primary substrate.	catechol	111-119	catechol oxidase B, chloroplastic	Solanum tuberosum	34-37	
32447731-8	2020	PPO and a chromophore reagent (3-methyl-2-benzothiazolinone hydrazine) generated a range of color in the presence of phenolic compounds (catechol, phenol, p-cresol, 4-methyl catechol) within 15 min, and limit of detection was found to be 0.5 muM.	catechol	137-145	catechol oxidase B, chloroplastic	Solanum tuberosum	0-3
