| mating type gene | Genes that, in Saccharomyces cerevisiae specify into which of the two mating types (a and _) a particular cell falls. Only unlike mating type haploids will fuse. The interest derives from the way in which mating type is switched, the existing gene is removed and a new gene, derived from a (silent) master copy elsewhere in the genome is spliced in. Later this gene will in its turn be replaced by a new copy of the old gene, also derived from a silent master. The a and _ genes code for pheromones that affect cells of the opposite mating type. Similar mating type genes are known from other yeasts and the switching mechanism (cassette mechanism) may be used more generally. (18 Nov 1997) |

| matrix metalloproteinase |
A member of a group of enzymes that can break down proteins, such as collagen, that are normally found in the spaces between cells in tissues (ie, extracellular matrix proteins). Because these enzymes need zinc or calcium atoms to work properly, they are called metalloproteinases. Matrix metalloproteinases are involved in wound healing, angiogenesis, and tumor cell metastasis.

| matrix band |
a cylindrical stainless steel or copper band or short tube with a special clamp or holder; it is filled with a softened impression compound and seated over a tooth, so that the compound flows into the prepared cavity and an impression of a single tooth can be obtained. Also used in the placement and contouring of restorative materials such as resin or glass ionomer cement, and to form the fourth wall of a class II cavity preparation during the condensation of an amalgam restoration.
