Metabolite Identification

Common Name

5-Methylcytosine

Description

5-Methylcytosine is a methylated nucleotide base found in eukaryotic DNA. In animals, the DNA methylation of cytosine to form 5-methylcytosine is found primarily in the palindromic sequence CpG. In plants, the methylated sequence is CpNpGp, where N can be any base. -- Pubchem; 5-Methylcytosine is a methylated form of cytosine in which a methyl group is attached to carbon 5, altering its structure without altering its base-pairing properties. -- Wikipedia ; 5-Methylcytosine is an epigenetic modification formed by the action of DNA methyltransferases. In bacteria, 5-methylcytosine can be found at a variety of sites, and is often used as a marker to protect DNA from being cut by native methylation-sensitive restriction enzymes. In plants, 5-methylcytosine occurs at both CpG and CpNpG sequences. In fungi and animals, 5-methylcytosine predominately occurs at CpG dinucleotides. Although most eukaryotes methylate only a small percentage of these sites, in vertebrates 70-80% of CpG cytosines are methylated. -- Wikipedia .

Enzymes

Enzyme Details

1. DNA (cytosine-5)-methyltransferase 3A

General function:: Involved in DNA binding
Specific function:: Required for genome-wide de novo methylation and is essential for the establishment of DNA methylation patterns during development. DNA methylation is coordinated with methylation of histones. It modifies DNA in a non-processive manner and also methylates non-CpG sites. May preferentially methylate DNA linker between 2 nucleosomal cores and is inhibited by histone H1. Plays a role in paternal and maternal imprinting. Required for methylation of most imprinted loci in germ cells. Acts as a transcriptional corepressor for ZNF238. Can actively repress transcription through the recruitment of HDAC activity (By similarity).
Gene Name:: DNMT3A
Uniprot ID:: Q9Y6K1
Molecular weight:: 101857.595

Enzyme Details

2. DNA (cytosine-5)-methyltransferase 3B

General function:: Involved in DNA binding
Specific function:: Required for genome-wide de novo methylation and is essential for the establishment of DNA methylation patterns during development. DNA methylation is coordinated with methylation of histones. May preferentially methylates nucleosomal DNA within the nucleosome core region. May function as transcriptional co-repressor by associating with CBX4 and independently of DNA methylation. Seems to be involved in gene silencing (By similarity). In association with DNMT1 and via the recruitment of CTCFL/BORIS, involved in activation of BAG1 gene expression by modulating dimethylation of promoter histone H3 at H3K4 and H3K9. Isoforms 4 and 5 are probably not functional due to the deletion of two conserved methyltransferase motifs. Function as transcriptional corepressor by associating with ZHX1.
Gene Name:: DNMT3B
Uniprot ID:: Q9UBC3
Molecular weight:: 81309.795

Enzyme Details

3. tRNA (cytosine(38)-C(5))-methyltransferase

General function:: Involved in DNA binding
Specific function:: Specifically methylates cytosine 38 in the anticodon loop of tRNA(Asp).
Gene Name:: TRDMT1
Uniprot ID:: O14717
Molecular weight:: 44596.17

Enzyme Details

4. tRNA (cytosine(34)-C(5))-methyltransferase

General function:: Involved in tRNA (cytosine-5-)-methyltransferase activity
Specific function:: RNA methyltransferase that methylates tRNAs, and possibly RNA polymerase III transcripts. Methylates cytosine to 5-methylcytosine (m5C) at position 34 of intron-containing tRNA(Leu)(CAA) precursors. Not able to modify tRNAs at positions 48 or 49. May act downstream of Myc to regulate epidermal cell growth and proliferation. Required for proper spindle assembly and chromosome segregation, independently of its methyltransferase activity.
Gene Name:: NSUN2
Uniprot ID:: Q08J23
Molecular weight:: 82392.405

Enzyme Details

5. Cytosine-specific methyltransferase

General function:: Involved in DNA binding
Specific function:: S-adenosyl-L-methionine + DNA = S-adenosyl-L- homocysteine + DNA containing 5-methylcytosine
Gene Name:: Not Available
Uniprot ID:: Q59FP7
Molecular weight:: 182018.2
