Gout
|
is caused by an increase in uric acid production.
|
|
ADA deficiency (Adenosine Deaminase deficiency)
|
accounts for 15% of all SCIDs patients. ADA is the enzyme responsible for the conversion of adenosine to inosine in the breakdown of AMP.
|
|
Lesch-Nyhan Syndrome
|
is due to a deficiency in HGPRT (Hypoxanthine-Guanine Phosphoribosyl Transferase).
|
|
Ribose-5-Phosphate
|
Produced from Pentose Phosphate Pathway and is used in the synthesis of both ATP and GTP.
|
|
PRPP synthetase
|
is the first step in the conversion of Ribose-5-phosphate to PRPP (Phosphoribosyl-1-Pyrophosphate).
|
|
IMP-Inosine monophosphate
|
is the branch point in the purine nucleotide pathway.
|
|
PRPP synthease is regulated by AMP
|
True, ADP and ATP as well.
|
|
PRPP synthease is regulated by GMP
|
True
|
|
PRPP synthease is regualted by GTP
|
True
|
|
PRPP synthease is regulated by ADP
|
True
|
|
HGPRT
|
is the enzyme responsible for the conversion of Guanine to GMP and is deficient in Lesch-Nyhan Syndrome.
|
|
APRT
|
is the enzyme responsible for the conversion of adenine to AMP.
|
|
High Uric Acid levels
|
are a common sign of gout.
|
|
CPS-II
|
is responsible for the conversion of glutamine, carbon dioxide, and ATP to carbamoyl phosphate.
|
|
Ribonucleotide reductase
|
is responsible for the removal of the 2' OH group from the ribose sugar.
|
|
Thymidylate Synthase
|
is responsible for the conversion of dUMP to dTMP.
