YCF3 is essential for the assembly of the photosystem I (PSI) complex. In Chlamydomonas reinhardtii, it seems to act as a PSI specific chaperone facilitating the assembly of the complex by interacting with PsaA and PsaD.
RP- L24, PLASTID RIBOSOMAL PROTEIN L24, RPL24, SUPPRESSOR OF VARIEGATION 8, SVR8
Background:
50S ribosomal protein L24 (RP-L24) is one of two assembly initiator proteins, it binds directly to the 5'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit.
pTAC12, HEMERA, HMR, PLASTID TRANSCRIPTIONALLY ACTIVE 12, TAC12
Background:
In chloroplasts, transcription of plastid genes is mediated by two types of RNA polymerase: plastid-encoded RNA polymerase (PEP) and nuclearencoded RNA polymerase (NEP). Transcription in plastids is also mediated by a number of nuclear-encoded factors in addition to PEP and NEP. In the insoluble RNA polymerase preparation samples, a total of 18 components named as pTACs (pTAC1 to pTAC18) were identified. pTAC12 (AT2G34640) is one of the components associated with PEP complex.
ADP-glucose pyrophosphorylase (ADGP) is the catalytic isoform responsible for ADP-glucose pyrophosphorylase activity. The presence of ADGP is required for large subunit stability. ApS1 is the major small subunit isoform present in all plant tissues tested.
VTC2, GDP-L-GALACTOSE PHOSPHORYLASE, GGP, VITAMIN C DEFECTIVE 2
Background:
VTC2 is a novel protein involved in ascorbate biosynthesis, which was shown to catalyze the transfer of GMP from GDP-galactose to a variety of hexose-1-phosphate acceptors.
FTSH4 is an FtsH protease that is localized to the mitochondrion. Loss of function results in increased determinacy of the meristem that is exacerbated when plants are grown at higher temperatures.
