Tryptophan indole-lyase (Trpase), PBPRA2532, from Photobacterium profundum SS9, a piezophilic marine bacterium, has been cloned, expressed in Escherichia coli, and purified. The P. profundum Trpase (PpTrpase) exhibits similar substrate specificity as the enzyme from E. coli (EcTrpase). PpTrpase has an optimum temperature for activity at about 30°C, compared with 53°C for EcTrpase, and loses activity...
During the lifetime of an angiosperm plant various important processes such as floral transition, specification of floral organ identity and floral determinacy, are controlled by members of the MADS domain transcription factor family. To investigate the possible non‐cell‐autonomous function of MADS domain proteins, we expressed GFP‐tagged clones of AGAMOUS (AG), APETALA3 (AP3), PISTILLATA (PI) and...
