Posttranslational Modification | Comment | Organism |
---|---|---|
proteolytic modification | panD is initially translated as inactive precursor pi-protein which is slowly proteolytically cleaved at a specific Gly-Ser bond producing two dissimilar subunits, autocatalytic mechanism | Escherichia coli |
proteolytic modification | the panD gene product is efficiently proteolytically processed into two subunits, an 11 kDa alpha-subunit and a 2.7 kDa beta-subunit, Gly-24/Ser-25 may be the processing site of the initially translated pi-protein | Corynebacterium glutamicum |
