at the C-terminal this lyses Alanine, Leucine, Isoleucine, Valine
Term
carboxypeptidase B
Definition
at the C-terminal this lyses Arginine or Lysine
Term
Alanine, Glycine, and Serine

Elastase, which is activated by trypsin, lyses what three AA on the C-side?
Term
Vitamin B6
Definition
Amino acids require pyridoxal phophate which is derived from?
Term
ALT
Definition
Alanine and alpha-ketoglutarate are the reactants and pyruvate and glutamate are the products of this enzyme
Term
AST
Definition
OAA and Glutamate are the reactants and Asparate and alpha ketoglutarae are the products of this enzyme
Term
ketogenics
Definition
Leucine, Lycine, and Tryptophan are the major?
Term
cystinuria
Definition
AR disorder where cystine cant be reabsorbed and leadds to stones of cystine in the urinary tract
Term
Lysine and threonine
Definition
all of the amino acids except these two participate in transamination
Term
glutamate dehydrogenase
Definition
NAD+ and NADP can be used as coenzymes for this enzyme
Term
GTP
Definition
what is the allosteric inhibitor of glutamate dehydrogenase?
Term
ADP
Definition
what is the allosteric activator of glutamate dehydrogenase?
Term
glutamate

what is the activator of NAG
Term
3
Definition
how many molecules of ATP are consumed in the formation of UREA
Term
neomycin
Definition
reduces the number of intestinal bacteria responsible for NH3 production
Term
4
Definition
how many high energy phosphates are consumed in the synthesis of each mole of urea?
Term
phenylbutyrate
Definition
carbamoyl phosphate synthestase I deficiency is treated with?
Term
carbomyl phophate synthetase I
Definition
a deficiency in this enzyme, leads to the inability for nitrogenous waste to be metabolized in the urea cycle
Term
Orthinine Transcarbomylase
Definition
a deficiency in this enzyme leads to a inability for nitrogenous waste to be metabolized and is associated with X-linked inheritance
Term
arginosuccinate synthase
Definition
a deficiency in this enzyme leads to a elevated serum citrulline count associated with hypotonia, ataxia, and behavioral changes
Term
arginosuccinate lyase
Definition
a deficiency in this enzyme leads to hyperammonemia and has huge effects on the CNS
Term
arginase
Definition
if there is a deficiency in this enzyme there will be no hyperammonemia and there will be restoration of the pathway
