Biochemical Characterization of Bovine Brain Myristoyl‐CoA:Protein N‐Myristoyltransferase Type 2
Bibliographic record
Abstract
Protein N-myristoylation is a lipidic modification which refers to the covalent attachment of myristate, a 14-carbon saturated fatty acid, to the N-terminal glycine residue of a number of mammalian, viral, and fungal proteins. In this paper, we have cloned the gene coding for myristoyl-CoA:protein N-myristoyltransferase (NMT) from Bos tarus brain. The open reading frame codes for a 410-amino-acid protein and overexpressed in Escherichia coli. Kinetic studies suggested that bovine brain NMT2 and human NMT1 show significant differences in their peptide substrate specificities. The metal ion Ca(2+) had stimulatory effects on NMT2 activity while Mn(2+) and Zn(2+) inhibited the enzyme activity. In addition, NMT2 activity was inhibited by various organic solvents and other detergents while NMT1 had a stimulatory effect. Biochemical characterization suggested that both forms of NMT have unique characteristics. Further analysis towards functional role NMT2 will lead the development of therapeutic target for the progression of various diseases such as cancer, cardiovascular diseases, and neurodegenerative diseases.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
