ABSTRACT
Unfortunately there is a large discrepancy between the rapidly expanding number of pectate and pectin lyases encoding nucleotide sequences available nowadays, and the actual number of corresponding enzymes thoroughly characterized biochemically. For many pectate and pectin lyases which have been biochemically characterized in the past no nucleotide sequences are available. This makes it difficult to relate certain biochemical properties to a particular family. However, biochemical data are available for at least one member of each of the six pectate lyase families. These will be discussed later.
