Methylcytosine undergoes spontaneous deamination, at a rate much higher than cytosine, to generate thymine.

甲基化胞嘧啶在生理条件下极易发生自发脱氨，生成胸腺嘧啶，产生G/T错配。

Technologies for determining methylation patterns in cancer cells, Methyl Light and COBRA, both of which were based on the deamination of methylated cytosines—which converts these cytosines to uracil residues—and identification of the converted sequence by analytical methods.

在上世纪80年代期间，研究的主要方法是PCR和克隆，两者都不涉及甲基化内容，因此很快就被弃用了。90年代，Laird开发了两类技术去检测肿瘤细胞中的甲基化模式，MethylLight和COBRA，两者都是以甲基化胞嘧啶的脱氨作用（将胞嘧啶转化为尿嘧啶残基）以及通过分析方法鉴定修改的序列为基础。

Uracil also can be introduced by hydrolytic deamination of cytosine which paired with guanine. Highly mutagenic dU:dG mispair may cause a C→T transition mutation upon replication if it was not repaired.

另一种可能则是由胞嘧啶(Cytosine； C)发生自发性或氧化脱胺反应而形成尿嘧啶与鸟粪嘌呤的配对错误。

The facts that type I compounds could easily undergo deamination reaction to form α-methylene cyclopentanone derivatives and they could react with glutathione to form an adduct provided sufficient evidence for the hypothesis that the compounds acted as masked α-methylenecyclopen- tanones and reacted with biologically important sulfhydry-containing enzymes, and thus produced anticancer activity.

Ⅰ类化合物在稀溶液中极易进行去胺基化反应形成α-亚甲基环戊酮类化合物。并且Ⅰ类化合物于稀溶液中易与谷胱苷肽进行结合，这些事实为Ⅰ类化合物作为隐蔽的α-亚甲基环戊酮与酶进行加成，从而导致酶失活而具有抗癌活性的设想提供了证据。

In rabbit plasma, there were two kinds of SSAO, which could catalyze the oxidative deamination of methylamine into formaldehyde, had significantly different kinetic parameters.

兔血浆含有两种SSAO酶，均可以催化甲胺氧化脱氨生成甲醛；组分A、B动力学特征有所不同。关键词氨基脲敏感型胺氧化酶；甲胺；酶动力学

Guanosine monophosphate reductase catalyzes the NADPH-dependent reductive deamination of Guanosine monophosphate to inosine monophosphate .

鸟苷酸还原酶(guanosine monophosphate reductase，GMPR)(EC 1.6.6.8)主要催化鸟嘌呤核苷酸向次黄嘌呤核苷酸的转化：GMP+NADPH+2〓→IMP+〓+NADP〓。

Over the AlPO〓, the deamination and dealkylation of diethylmine and triethylmine produced ethylene selectivily. Over AlPONs of acid-base bifunctional catalysts the ethylnitrol formed selectivily.

二乙胺、三乙胺在酸性的磷酸铝上选择性的脱烷基/脱氨生成乙烯，在酸碱两性的氮化磷酸铝上选择性脱烷基/脱氢生成乙腈。

To study the applicable prospect of suicide gene on tumor therapy in clinic,we cloned the gene of D-amino acid oxidase and the gene of yeast cytosine deaminase.We hope to establish the transgenic mices of DAAO gene and YCD gene,and the two transgenic strain mices are valuable animal system for studying the biological characteristic of DAAO gene and YCD gene ,for studing the killing activity of DAAO/D-Ala and YCD/5-FC gene therapy systems on tumor.The D-amino acid oxidase gene derived from R.gracilis and it could oxidize D-amino acids. Hydrogen peroxide(H2O2) is a reactive oxygen species generated in the deamination of D-Ala catalyzed by DAAO.
