Description:
mysqldump --user=root -p --databases information_schema > information_schema_test.sql
OR
mysqldump --no-data  --databases information_schema --user=root -p > information_schema .sql

gives mysqldump: Got error: 1044: Access denied for user 'root'@'localhost' to database 'information_schema' when using LOCK TABLES

How to repeat:
rerun mysqldump on information_schema

Please, try to add --skip-lock-tables option to the command line. Check http://dev.mysql.com/doc/refman/5.5/en/mysqldump.html:

"mysqldump does not dump the INFORMATION_SCHEMA database by default. mysqldump dumps INFORMATION_SCHEMA only if you name it explicitly on the command line, although currently you must also use the --skip-lock-tables option."
