Indeed, the biotinylation is a post-translational modification that allows the transformation of inactive biotin-dependent carboxylases, which are committed in fundamental metabolisms such as fatty acid synthesis, into their active holo form. Among other living organisms, plants present a peculiarly complex situation. In pea, HCS activity has been detected in three subcellular compartments and the systematic sequencing of the Arabidopsis genome revealed the occurrence of two hcs genes (hcs1 and hcs2). Hcs1 gene product had been previously characterized at molecular and biochemical levels. Here, by PCR amplification, we cloned an hcs2 cDNA from Arabidopsis thaliana (Ws ecotype) mRNA. We observed the occurrence of multiple cDNA forms which resulted from the alternative splicing of hcs2 mRNA. Furthermore, we evidenced a nucleotide polymorphism at the hcs2 gene within the Ws ecotype, which affected splicing of hcs2 mRNA. This contrasted sharply with the situation at hcs1 locus. However, this polymorphism had no apparent effect on total HCS activity in planta. Finally, hcs2 mRNAs were found 4-fold less abundant than hcs1 mRNA and the most abundant hcs2 mRNA spliced variant should code for a truncated protein. We discuss the possible role of such a multiplicity of putative HCS proteins in plants and discuss the involvement of each of hcs genes in the correct realization of biotinylation."xsd:string |
