|
SOD
|
reactive O2* -> H2O2
|
|
|
Myeloperoxidase
|
H2O2 -> HOCl*
(makes bleach to kill bac) |
|
|
Catalase
|
H2O2 -> H2O
(neutralizes excess peroxide) |
|
|
NADPH oxidase
|
O2 -> O2*
(makes reactive O2 species, NADPH becomes NADP+ as a result of this enzymatic rxn) |
|
|
aldose reductase
|
glucose -> sorbitol
(lens, retina, schwann, seminal vesicles) **Hyperglycemia-> inc glucose in cell, add NADPH and aldose reductase makes sorbitol, which gets trapped inside, accumulates -> osmotic swelling -> cataracts, peripheral neuropathy in diabetes) |
|
|
Acidic amino acids
|
Asp, Glu
(acidic AA are NEGATIVELY charged) |
|
|
Basic amino acids
|
Arg, Lys
(basic AA are POSITIVELY charged; this is why histones bind negatively-charged DNA so well) |
|
|
Which AAs have extra NH3 group?
|
Arg, Lys
|
|
|
Which AA is most basic? (=most positive)
|
Arg
|
|
|
Which AA is involved in vasodilation?
|
Arg
(Arg + NOS -> NO) |
|
|
Which AA has no net charge?
|
His
(a basic amino acid) |
|
|
Why is hyperammonemia bad?
|
alpha-ketoglutarate+NH3 <=>glutamate
excess NH3 makes more glutamate and less alpha-KG, which is needed for TCA, which the brain depends on (NH3 steals energy from the brain) |
|
|
DNA polymerase I
|
polymerization of nucleotides; also functions in processing and repair mechanisms
|
|
|
DNA polymerase III
|
major replicating enzyme in e.coli?
|
|
|
chiasma
|
cross-like structure formed when 2 homologous chromosomes exchange material
|
|
|
synapsis
|
proper name for the pairing of homolougous chromosomes with which meiosis begins
|
|
|
Tripolar mitoses
|
abnl mitoses resulting from abnl mitotic spindles
-in tumor cells, evidence of malignancy |
|
|
AAUAAA
|
sequence that must be recognized in order for mRNA polyadenylation to occur
|
