Sammanfattning : Ribonucleotide reductase (RNR) is a key enzyme for de novo dNTP biosynthesis. We have studied nucleotide-dependent oligomerization of the allosterically regulated mammalian RNR using a mass spectrometry–related technique called Gas-phase Electrophoretic Mobility Macromolecule Analysis (GEMMA).

Sammanfattning : Chromatin is a highly dynamic, regulatory component in the process of transcription, repair, recombination and replication. The BRG1 and SNF2H proteins are ATP-dependent chromatin remodeling proteins that modulate chromatin structure to regulate DNA accessibility for DNA-binding proteins involved in these processes.

3. Two Types of Fibrils in ATTR Amyloidosis : Implications for Clinical Phenotype and Treatment Outcome
Sammanfattning : Systemic amyloidoses are a group of lethal diseases where proteins aggregate into fibrillar structures, called amyloid fibrils, that deposits throughout the body. Transthyretin (TTR) causes one type of amyloidosis, in which the aggregates mainly infiltrate nervous and cardiac tissue. LÄS MER
4. Proteins of the Inter-α-inhibitor Family : Biosynthesis, Plasma Clearance and Interaction with Extracellular Matrix Components
Sammanfattning : Bikunin, a chondroitin sulfate-containing protein of 25 kDa, has protease inhibitory activity and occurs in the plasma in free and complexed form. In inter-α-inhibitor (IαI) and pre-a-inhibitor (PαI) it is covalently linked through its chondroitin sulfate (CS) chain to two or one other polypeptide of about 80 kDa – heavy chains 1 and 2 (H1, H2) and heavy chain 3 (H3) – respectively.

Sammanfattning : Proteins are a structurally diverse and functionally versatile class of biomolecules. They perform a variety of life-sustaining biological processes with utmost efficiency. A profound understanding of protein function requires knowledge of its structure. LÄS MER
