amino acid/nucleotide synthesis Flashcards
what are the reactions in amino acid/nucleotide synthesis
1 carbon transfer reactions
what does S-adenosyl methionine do
donates a methyl group
whats the principle molecule used in amino acid/nucleotide synthesis
tetrahydrofolate
can we make tetrahydrofolate
no
where do the carbon 1 units get added on tetrahydrofolate
N5 and N10
what section is the N5 on
6-methypterin
what section is the N10 on
p-aminobenzoate
what does homocysteine become
methionine with the addition of N5
whats the substrate of methionine synthase
homocysteine
what does glycine become
serine with the addition of N5, N10
what is methionine the precursor of
S-adenosylmethionine
whats the most important methyl donor in metabolic reactions
S-adenosylmethionine
methionine + ATP becomes what
S-adenosylmethionine
how is S-adenosylmethionine linked to methionine
at the C5 ribose atom
where does the methyl group on methionine come from
N5
