Metalloproteases> enzymes that comprise a diverse super family of proteases.

Metal ion in their catalytic sites.

Shape and modify extracellular matrix (ECM).

Irregularities can cause tumor formations, metastasis, and other diseases.

Human MMPs are a family of 23 enzymes.

Facilitate turnover and breakdown of the ECM in both physiology and pathology processes.

Native from Borneo

Arboreal specie

Length of 1.5 meters aprox.

Threatened specie

Genomic DNA used for this experiment

Problem How can we control irregularities in

metalloprotease’s enzymatic activity?

Hypothesis By the inhibition of the metalloprotease gene, the

irregularities of metalloprotease enzymes can be controled.

Analyze metalloprotease gene sequence for recording.

Bring valuable information related to global health issue.

Short term goals: Obtain a purified gene with desired gene to send for

sequencing

Long term goals: Send purified gene to sequence Determine the sequence of the MP gene in Pongo

pygmaeus genomic DNA Do a protease detection

Transform plasmid with MP gene to E. coli

Grow cells with plasmid DNA in liquid culture

Purify the plasmid DNA from the culture

Perform a plasmid minipreps

Send purified gene to bioinformatics

Do a protease detection

Transformation> Insert the plasmid into the vector (E. coli)

Plasmid Purification> Extract the replicated plasmid from the vector

Miniprep> Produce small quantities of purified plasmid
