FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Polymerization of Cycloolefines
Kobunshi Kagaku, 1969 1, 3-シクロオクタジエソ (1, 3-COD) と液体亜硫酸 (SO2) との共重合について検討した。1, 3-CODはAgNO3, H2O2などの添加によりSO2と共重合し, DMF, DMSOおよびSO2に可溶な1: 1組成のポリスルポソを与える。共役二重結合へのSO2の付加は主に1, 2-付加であろうと推定した。AgNO3を触媒とし, 過剰のSO2中で重合を行なった場合共重合初速度はAgNO3初濃度の1/2乗に比例し (0℃), 活性化エネルギーは約8.5kcal/mol (-10-+15℃) であった。重合初速度は約20℃に極大を有し, それ以上の温度では急激に低下し, 天井温度が35-40℃付近に存在することがわかった ([1, 3-COD] 0・[SO2] 0=10mol2/l2 ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Polymerization-Induced Self-Assembly Promoted by Liquid–Liquid Phase Separation
, 2019 Polymerization-induced self-assembly (PISA) is a powerful method for the synthesis of polymeric kinetically frozen core nanoparticles. However, the PISA synthesis of biologically important polymeric fluidic materials is unexplored.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified
