CC -!- FUNCTION: ATP-dependent specificity component of the Clp protease
CC complex. Hydrolyzes ATP. Targets specific substrates for degradation by
CC the Clp complex. Can perform chaperone functions in the absence of
CC CLPP. Enhances the DNA-binding activity of TFAM and is required for
CC maintaining a normal mitochondrial nucleoid structure. ATP-dependent
CC unfoldase that stimulates the incorporation of the pyridoxal phosphate
CC cofactor into 5-aminolevulinate synthase, thereby activating 5-
CC aminolevulinate (ALA) synthesis, the first step in heme biosynthesis.
CC Important for efficient erythropoiesis through up-regulation of heme
CC biosynthesis. {ECO:0000250|UniProtKB:O76031}.
CC -!- SUBUNIT: Homohexamer that forms a ring structure; this hexamerization
CC requires ATP binding. Component of the Clp complex formed by the
CC assembly of two CLPP heptameric rings with two CLPX hexameric rings,
CC giving rise to a symmetrical structure with two central CLPP rings
CC flanked by a CLPX ring at either end of the complex. Interacts with
CC TFAM. {ECO:0000250|UniProtKB:O76031}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000250}. Mitochondrion
CC matrix, mitochondrion nucleoid {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the ClpX chaperone family. {ECO:0000255|PROSITE-
CC ProRule:PRU01250}.
