! Can anyone advise me on how to gain access to the databank
!on restriction enzymes? I only have a dumb terminal, so WAIS is out
!of the question. I tried SWAIS but had no luck. I also tried Archie
!and there seems to be something in an FTP site in Japan, but the
!path which Archie described didn't want to work when I tried to get
!it via FTP. Thanks for any replies.

RESTRICTION ENZYME DATABASE (REBASE)
The Restriction Enzyme Database, REBASE, is a repository of information
about the known restriction enzymes, methylases, and the microorganisms
from which they have been isolated. Documents (from 1952-present) that
describe the isolation of an enzyme or contribute observations relating
to an enzyme's properties are logged in REBASE, along with other useful
information, such as the commercial availability of the enzymes.
--------------------------
REBASE updates (ASCII flat files) are distributed electronically, at
monthly intervals and at no charge. These are available in many output
formats. Other formats can be provided upon request. We are prepared
to support each major sequence analysis package.
For those of you on the internet, an anonymous FTP site is now available.
The command "ftp rna.cshl.org" will get you in. In response to user name
just type "anonymous" or "ftp". Our REBASE files can then be found in the
directory pub/rebase. All of the files that we distribute electronically
will be kept there, along with any other related information.

2. --- ALL ENZYMES (REFERENCE LIST) ---
-------------------------------------------------------------------------------
DESCRIPTION:
A list of all restriction enzymes - Types I, II, and III.
References are numbered and listed seperately at the bottom
of the report.
EXAMPLE:
<1>ENZYME NAME: self explanatory
<2>PROTOTYPE: The name of the first enzyme discovered with this specificity.
<3>MICROORGANISM: self explanatory
<4>SOURCE: Either an individual or a National Culture Collection.
<5>RECOGNITION SEQUENCE: These are written from 5' to 3', only one strand being
given, and the point of cleavage is indicated ^. When no ^ appears, the
precise cleavage site has not been determined. For enzymes such as HgaI,
MboII etc., which cleave away from their recognition sequence the sites of
cleavage are indicated in parentheses. For example HgaI GACGC (5/10)
indicates cleavage as shown below
5' GACGCNNNNN^ 3'
3' CTGCGNNNNNNNNNN^ 5'
In all cases the recognition sequences are oriented so that the cleavage sites
lie on their 3' side.
Recognition sequences are given using the standard abbreviations (Eur. J.
Biochem. 150: 1-5, 1985) to represent ambiguity.
R = G or A
Y = C or T
M = A or C
K = G or T
S = G or C
W = A or T
B = not A (C or G or T)
D = not C (A or G or T)
H = not G (A or C or T)
V = not T (A or C or G)
N = A or C or G or T
<6>METHYLATION SITE: The site of methylation by the cognate methylase when known
is indicated as follows. The first number shows the base within the
recognition sequence that is modified. A negative number indicates the
complementary strand, numbered from the 5' base of that strand. The number in
parentheses indicates the specific methylation involved. (6) = N6-
methyladenosine (5) = 5-methylcytosine (4) = N4-methylcytosine.
<8>COMMERCIAL AVAILABILITY: commercial abbreviations as assigned in REBASE
<9>REFERENCES: only the primary references for the isolation and/or purification
of the restriction enzyme or methylase, the determination of the recognition
sequence and cleavage site or the methylation specificity are given.

the references at the bottom of the report, each enzyme
is followed by its reference information.
