Descriptions

  • Description Encodes a protein that promotes splicing of type II introns. otp51 mutants fail to splice intron 2 of plastid ycf3 transcripts, a factor required for the assembly of Photosystem I. Therefore, homozygous otp51 mutants have profound photosynthetic defects and can only survive in sucrose-supplemented in vitro cultures under low light conditions. OTP51 may also be involved in splicing several other transcripts and precursor forms of the trnL, trnG, trnI, and trnA transcripts also accumulate in otp51 mutants. Although OTP51 shares some homology with DNA endonucleases, it lacks key catalytic residues suggesting that it does not participate in DNA cleavage. | ORGANELLE TRANSCRIPT PROCESSING 51 (OTP51) | FUNCTIONS IN: endonuclease activity | INVOLVED IN: photosystem I assembly, nuclear mRNA cis splicing, via spliceosome, Group II intron splicing | LOCATED IN: chloroplast | EXPRESSED IN: 21 plant structures | EXPRESSED DURING: 13 growth stages | CONTAINS InterPro DOMAIN/s: Pentatricopeptide repeat , LAGLIDADG DNA endonuclease | BEST Arabidopsis thaliana protein match is: Pentatricopeptide repeat (PPR) superfamily protein
