EOG8V45NR GO:0004222 13/40 metalloendopeptidase activity molecular_function "Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions." [GOC:mah, http://merops.sanger.ac.uk/about/glossary.htm#CATTYPE, http://merops.sanger.ac.uk/about/glossary.htm#ENDOPEPTIDASE] EOG8V45NR GO:0008270 10/40 zinc ion binding molecular_function "Interacting selectively and non-covalently with zinc (Zn) ions." [GOC:ai] EOG8V45NR GO:0005578 10/40 proteinaceous extracellular matrix cellular_component "A layer consisting mainly of proteins (especially collagen) and glycosaminoglycans (mostly as proteoglycans) that forms a sheet underlying or overlying cells such as endothelial and epithelial cells. The proteins are secreted by cells in the vicinity. An example of this component is found in Mus musculus."

[GOC:BHF, GOC:TermGenie] EOG8V45NR GO:0007508 1/40 larval heart development biological_process "The process whose specific outcome is the progression of the larval heart over time, from its formation to the mature structure. In Drosophila the larval heart (dorsal vessel) is a continuous tube of mesodormal cells that runs beneath the dorsal midline of the epidermis, divided into an anterior aorta and a posterior heart proper."
