Molecular basis for the P450-catalyzed C-N bond formation in indolactam biosynthesis.

abstract：:F(1)-ATPase is an ATP-driven rotary motor protein in which the γ-subunit rotates against the catalytic stator ring. Although the reaction scheme of F(1) has mostly been revealed, the timing of inorganic phosphate (P(i)) release remains controversial. Here we addressed this issue by verifying the reversibility of ATP h...

abstract：:The plant hormone auxin regulates virtually every aspect of plant growth and development. Auxin acts by binding the F-box protein transport inhibitor response 1 (TIR1) and promotes the degradation of the AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA) transcriptional repressors. Here we show that efficient auxin binding requires...
