| Application: | It was used in enzymatic assay to measure citrate concentration using microtiter plates. |
| General description: | Citrate lyase is considered as a substrate- induced enzyme which helps in catalyzing reversible aldol cleavage of citrate to oxaloacetate and acetate. The enzyme is adaptive to anaerobic dissimilation of citrate. |
| Other Notes: | For life science research only. Not for use in diagnostic procedures. |
