Enzyme Function | FUNCTION: Molecular chaperone that interact with a ClpP-like protease involved in degradation of denatured proteins in the chloroplast (PubMed:21737456). The ATPase activity of CLPD is stimulated by CLPT1 (PubMed:25149061). Has no ADPase activity (PubMed:21737456). Interacts with transit peptides with a positional preference (PubMed:21737456, PubMed:22545953). Localization of the signal sequence at the N-terminal end of a protein seems mandatory for interaction to take place (PubMed:22545953). {ECO:0000269|PubMed:21737456, ECO:0000269|PubMed:22545953, ECO:0000269|PubMed:25149061}. |

Interact With | |
Induction | INDUCTION: By dehydration and salt stresses. Induced after one hour of dehydration-stress and reaches maximal levels after 10 hours. Induced by cold, ozone, senescence and dark-induced etiolation. Down-regulated by ozone (at protein level). Not induced by heat stress. {ECO:0000269|PubMed:10198079, ECO:0000269|PubMed:10427773, ECO:0000269|PubMed:10444084, ECO:0000269|PubMed:11982939, ECO:0000269|PubMed:17144892, ECO:0000269|PubMed:9375397}. |
