Heterologous plastoquinone production using a newly identified O2‐dependent cyanobacterial hydroxylase

The FEBS Journal, Volume 293, Issue 6, Page 1708-1726, March 2026.
In this study, we confirm that PlqH is the hydroxylase operating in plastoquinone biosynthesis in photosynthetic cyanobacteria (Cyanobacteriia). Our phylogenetic analyses demonstrate that cyanobacterial PlqH homologues originated from hydroxylases involved in ubiquinone biosynthesis in bacteria. Plastoquinone production in Escherichia coli was achieved

Evolution of lysine and arginine biosynthesis revealed by substrate specificity of lysine biosynthetic enzymes in Thermus thermophilus

The FEBS Journal, Volume 293, Issue 6, Page 1727-1740, March 2026.
Two enzymes from the Thermus thermophilus lysine biosynthetic pathway, LysZ and LysY, unexpectedly exhibit substrate promiscuity. They are able to recognize the LysW intermediates utilized by the ArgW‐mediated arginine route, even though the bacterium already possesses the canonical arginine biosynthetic pathway.

Structural investigation of human U6 snRNA recognition by spliceosomal recycling factor SART3 RNA recognition motifs

The FEBS Journal, Volume 293, Issue 5, Page 1323-1340, March 2026.
Human SART3 has two RRM domains to engage with U6 snRNA for spliceosome recycling. This study reports solution structures of SART3 RRM domains and investigates the interaction between RRM and U6 snRNA. SART3 binds to the asymmetric bulge of U6 snRNA as a dimer via conserved positively charged surfaces.

Binding of Bacillus subtilis dynamin‐like protein DynA to the bacterial membrane is essential for effective phage defense

The FEBS Journal, Volume 293, Issue 6, Page 1741-1753, March 2026.
The bacterial dynamin‐like protein DynA from Bacillus subtilis plays a key role in phage defense. It binds the plasma membrane through a unique paddle domain in its D1 subunit. This membrane association is essential for its protective function, likely preventing explosive membrane rupture following phage infection.

Leishmania donovani's protein tyrosine phosphatases interact with DUF21 and respond to environmental magnesium

The FEBS Journal, Volume 293, Issue 6, Page 1754-1770, March 2026.
The Leishmania phosphatase PTP1, and possibly the genetically similar PTP2, interacts with the Leishmania transmembrane protein DUF21. When both ptp1 and ptp2 are knocked out of Leishmania (LdΔPTP1/2), the parasite can no longer survive without magnesium in vitro and has reduced viability in the host macrophage. Conversely, in duf21 knockout (LdΔDUF21),
