Overview reactions and EC numbers

* Currently 445 EC classes have a "B" (from BRENDA) and 468 EC classes have a "M" or lower case letters (from MetaCyc) in the 4th position of the EC number. A part of these enzymes is in the reviewing process of the enzyme commission of the IUBMB and awaiting their EC numbers. Another part is waiting for more data which are a prerequisite for being proposed to the IUBMB (e.g. a description of the purification procedure). Incompletely classified "B-enzymes" (preliminary BRENDA-supplied EC numbers) mostly fill gaps in otherwise established pathways.
