Affinity chromatography of creatine phosphokinase on organomercurial‐sepharose [PDF]
Creatine phosphokinase (CPK, EC 2.7.3.2) occurs mainly in muscle where it catalyses the reversible transfer of phosphate between ADP and creatine phosphate [ 1 ] . The enzyme has been isolated by combining alcohol and salt fractionation [ 1 ] followed by DEAE-column chromatography [2,3] .

Phosphorylation of Optineurin by TBK1 induces the formation of filaments that condensate upon binding to linear polyubiquitin. Membrane‐anchored LC3 partitions into these condensates, suggesting that phase separation of filamentous Optineurin with ubiquitylated cargo promotes the sequestration of cargo and its subsequent alignment with LC3‐positive ...

Evaluation of the performance of affinity matrix produced from improved variants of S3 peptide to remove endotoxin from Active pharmaceutical ingredient of streptokinase and comparison with commercial matrices [PDF]
Introduction: Endotoxin or lipopolysaccharide (LPS) is one of the components of the wall of gram-negative bacteria, which, when in contact with blood, stimulates the immune system and causes fever and even serious adverse effects or death.

Purification and Characterization of a Chloroplast Outer-Envelope-Bound, ATP-Dependent Protein Kinase [PDF]
An ATP-dependent protein kinase was partially purified from isolated outer envelope membranes of pea (Pisum sativum L., Progress No. 9) chloroplasts. The purified kinase had a molecular weight of 70 kilodaltons, as determined by sodium dodecyl sulfate ...

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Purification of bovine pancreatic glucagon as a by-product of insulin production
A process for purifying bovine pancreatic glucagon as a by-product of insulin production is described. The glucagon-containing supernatant from the alkaline crystallization of insulin was precipitated using ammonium sulfate and isoelectric precipitation.

A mutant of Neurospora crassa deficient in cytochrome c heme lyase activity cannot import cytochrome c into mitochondria [PDF]
The nuclear cyt-2-1 mutant of Neurospora crassa is characterized by a gross deficiency of cytochrome c (Bertrand, H., and Collins, R. A. (1978) Mol. Gen. Genet. 166, 1-13).

The Disordered Region of ASXL1 Acts as an Auto‐Regulator Through Condensation
ASXL1's long IDR encodes an electrostatic “basic platform + acidic brake” that autoregulates condensation. Truncation at a clinical hotspot lifts this brake, forming condensates that retarget BRD2, remodel local chromatin accessibility, and impair neutrophil maturation.
