The correct option is C Lipase
Streptokinase is a protein obtained from Streptococcus bacteria. The protein enzyme helps in relieving blood clots in humans. This comes in handy when treating myocardial infarctions and brain hemorrhage.
Lipase is another protein that can be obtained from several bacteria. This is essentially an enzyme that digests lipids. Lipases come in handy in detergents that are designed in taking out the stains from clothes. Cytokinin, Somatostatin and Acetyl CoA are not proteins that are harnessed via transgenic microbes. Cytokinins are plant growth signalling molecules and Acetyl CoA is a secondary messenger molecule that interacts with other protein targets.
