An RNA-chaperone-like Protein in Chloroplasts

Jiang et al. isolated a plastid-localized RNA-chaperone-like protein and investigated its function. Plant Cell https://doi.org/10.1105/tpc.18.00946.  By Jingjing Jiang, Xin Chai, Nikolay Manavski, and Wei Chi  Background: RNA folding, which underlies the formation of RNA structure, is important…

BSD2 is a Rubisco specific assembly chaperone, forms intermediary hetero‐oligomeric complexes and is non‐limiting to growth in tobacco (Plant Cell Environ)

The rubisco holoenzyme is comprised of eight large subunits and eight small subunits (L8S8).  Several auxiliary proteins are required to correctly assemble the functional protein. In this manuscript, Conlan et al investigate the chaperone function of one of these proteins, BSD2, in tobacco. The authors…

Roles of RbcX in carboxysome biosynthesis in the cyanobacterium Synechococcus elongates PCC 7942  (Plant Physiol)

Introduction of the cyanobacterial carboxysome into C3 crops represents a viable strategy to increase photosynthetic conversion efficiency and boost crop yield.  Key to this challenge is gaining a full understanding of the carboxysome system in cyanobacteria, including how these microcompartments assemble…
