Critical amino acid residues in the N-terminal domain of NADPH-dependent assimilatory sulfite reductase flavoprotein mediate octameric assembly

The paper identifies critical amino acid residues in the N-terminal domain of SiRFP that mediate octameric assembly, revealing their role in stabilizing the enzyme's structure.

Structure of dimerized assimilatory NADPH-dependent sulfite reductase reveals the minimal interface for diflavin reductase binding

The paper determines the 2.78 Å resolution cryo-EM structure of Escherichia coli SiR, revealing the minimal interface for diflavin reductase binding and distinguishing between hemoprotein and ferredoxin partner interactions.
