| Enzyme Function | FUNCTION: ATP-dependent serine protease that mediates the selective degradation of mutant and abnormal proteins as well as certain short-lived regulatory proteins. Required for cellular homeostasis and for survival from DNA damage and developmental changes induced by stress. Degrades polypeptides processively to yield small peptide fragments that are 5 to 10 amino acids long. Binds to DNA in a double-stranded, site-specific manner (By similarity). In R.meliloti it is important for controlling the turnover of a constitutively expressed protein(s) that, when unregulated, disrupts normal nodule formation and normal growth. {ECO:0000255|HAMAP-Rule:MF_01973}. |
