Human Endogenous Metabolite

[体外研究]

麦芽糖是直链淀粉同源系列的两个单元成员,是淀粉的关键结构基序。当β-淀粉酶分解淀粉时,它一次除去两个葡萄糖单元,产生麦芽糖。在异构体异麦芽糖中,两个葡萄糖分子与α(1→6)键连接。

Direct recognition of the C-terminal polylysine residues of nonstop protein by Ltn1, an E3 ubiquitin ligase.

Biochem. Biophys. Res. Commun. 453(3) , 642-7, (2014)

When mRNAs lack stop codons, errors in gene expression and coding of aberrant proteins that are harmful in cells can result. In Saccharomyces cerevisiae, a 180-kDa E3-ubiquitin ligase, Ltn1 has been k...
