Improving the sensitivity of protein-protein interaction detection and protein structure probing is a principal challenge in cross-linking mass spectrometry (XL-MS) data analysis. In this talk, we pro...
Many of the biological materials that researchers are most interested in studying, including those associated with major diseases, don’t lend themselves to the conventional methods that researchers ty...
A typical bacterial genome contains more than 4,000 genes, which encode all of the proteins that the cells need to survive. How do cells know just how much of each protein they need for their everyday...
Protein controlled by both light and temperature can inform cell signal pathways（图）
蛋白质 细胞 信号通路

Most organisms have proteins that react to light. Even creatures that don’t have eyes or other visual organs use these proteins to regulate many cellular processes, such as transcription, translation,...
In food products, the natural blues tend to be moody.
锌在生物体中以离子（Zn2+）的形式存在，作为生物体必需的微量元素，Zn2+在发育、代谢、DNA合成和转录调控等生理和细胞过程中发挥着重要作用。在人体中，Zn2+与10%的总蛋白结合，或作为功能蛋白的结构成分（如锌指），或作为催化酶的辅因子。Zn2+缺乏会导致生长发育不良、先天性神经和免疫紊乱、伤口愈合不良、慢性炎症和出血等症状。反之，Zn2+过量对细胞也是剧毒的。
Combining state-of-the-art X-ray technology and cryogenics, Cornell physics researchers have developed a new method for analyzing proteins in action, a breakthrough that will enable the study of far m...

Artificial Enzyme Protein Designed Entirely Scratch Functions In Cells Life-Sustaining Catalyst
2018/2/1
A dawning field of research, artificial biology, is working toward creating a genuinely new organism. At Princeton, chemistryprofessor Michael Hecht and the researchers in his lab are d...
The effects of dietary protein intake on appendicular lean mass and muscle function in elderly men: a 10-wk randomized controlled trial
nutrient requirements dietary protein skeletal muscle older adults whole foods
2018/11/21
Background: The Recommended Daily Allowance (RDA) for protein intake in the adult population is widely promoted as 0.8 g · kg−1 · d−1. Aging may increase protein requirements, particularly...
Consumption of whole eggs promotes greater stimulation of postexercise muscle protein synthesis than consumption of isonitrogenous amounts of egg whites in young men
protein digestion food protein quality leucine amino acid transporters anabolic signaling exercise
2018/11/21
Background: Protein in the diet is commonly ingested from whole foods that contain various macro- and micronutrients. However, the effect of consuming protein within its natural whole-food matrix on p...
Quantity and source of dietary protein influence metabolite production by gut microbiota and rectal mucosa gene expression: a randomized, parallel, double-blind trial in overweight humans
dietary protein protein source high-protein diet gut microbiota
2018/11/19
Background: Although high-protein diets (HPDs) are frequently consumed for body-weight control, little is known about the consequences for gut microbiota composition and metabolic activity and for lar...
In the elderly, meat protein assimilation from rare meat is lower than that from meat that is well done
protein metabolism amino acid bioavailability meat cooking elderly
2018/11/20
Background: Meat cooking conditions in in vitro and in vivo models have been shown to influence the rate of protein digestion, which is known to affect postprandial protein metabolism in the elderly.
Within-day protein distribution does not influence body composition responses during weight loss in resistance-training adults who are overweight
exercise weight loss muscle mass heart health protein patterning
2018/11/20
Background: Emerging research suggests that redistributing total protein intake from 1 high-protein meal/d to multiple moderately high-protein meals improves 24-h muscle protein synthesis. Over time, ...
