共價修飾(Covalent Modification) - 小小整理網站 酶蛋白肽鏈上的一些基團可與某種化學基團發生可逆的共價結合，從而改變酶的活性，這一過程稱為酶的共價修飾或者化學修飾。在共價修飾過程中，酶無活性（或低活性）與有活性（或高活性）兩種形式的互變，這兩種互變由兩種催化不可逆反應的酶所 ...

Sandwalk: Regulating Enzyme Activity by Covalent Modification The codons are UGU and UGC—the Cys codons. Those are the ones recognized by phosphoseryl-tRNA because the phosphoserine is converted to cysteine while it's still attached to tRNA but before it is incorporated into protein. The codons though are still for

Probing Protein Structure by Amino Acid-Specific Covalent Labeling and Mass Spectrometry Cross-linking methods are similar to covalent labeling strategies in that the amino acid side chain modifications are not readily reversed. These methods create new intramolecular or intermolecular bonds that impose distance constraints on the location of

Posttranslational modification - Wikipedia, the free encyclopedia Posttranslational modification (PTM) is a step in protein biosynthesis. Proteins are created by ribosomes translating mRNA into polypeptide chains. These polypeptide chains undergo PTM (such as folding, cutting and other processes) before becoming the mat
Epigenetic Inhibitors : inhibitors of DNA methylation and histone covalent modification - InvivoGen InvivoGen provides inhibitors of epigenetic events, such as DNA methylation and covalent modification of histones. Epigenetic events have been demonstrated to silence the expression of many genes that suppress malignancy. Since the event is reversible, it
